"oh, we're using our made up names"

I'm really confused.

The Hail Mary is not a big ship. It took me less than 20 minutes to explore every room after I first woke up - and that's with having forgotten to walk after not moving a muscle in over four years. Just 20 minutes.

I've been looking for Rocky for over two hours now.

"Rocky?" I call out into the dormitory that I've already checked three times.

I frown with my hands on my hips.

We both have our days when we really need our own space. For the most part, we'll usually respect it and leave the other be as well as we can, but in living quarters this small and with a roommate who can hear through walls, me-time is always more of a we-time. Surprisingly, it hasn't been too bad. We both know what the alternative is like, and I think that's given us enough perspective to not just be tolerant of each other's constant presence, but straight up clingy for it. Even this late in the game. So I'm beginning to feel small-to-medium amounts of disturbed. I might not be able to see through walls, but I've never had trouble finding him before-

"What the-!"

I snap my head around, eyes bouncing from spot to spot. I feel the hairs of my neck stand and the flesh of my arm pimple with goosebumps.

There's nothing there. Nobody there. No Rocky there. Rocky is the only person who could be on the ship. Heh.

"Okay, buddy. If you're trying to mess with me because of what I said, I'm sorry! It's not gonna work!" I call out, trying my best to keep my voice from betraying the unease I feel in my gut. I feel like I'm being watched.

Before his sudden disappearance, Rocky and I had a bit of a discussion over who, in our scenario, would be the horrific monster alien that poses an extinction threat to the other's species, and who would be the chum. We've tallied up the points so far and learned the terrifying histories of each other's evolution and special adaptations. It got more and more heated as we tied in counter with each other over and over. I'd win the balancing on one foot contest, he'd win the 'has five legs and has no need for stupid balance' contest. So on and so forth.

After a few hours of this, my blood was up. I (cockily) suggested performing a live demonstration of a perfect monster for him when we touch down on Erid. I may have said something about getting the entire Eridian race under my squishy and opposable thumb. Starting with Rocky's mother.

So now Rocky's missing. For the first hour, I worried I took it a step too far. Maybe your mom jokes are a line you just don't cross in Eridian culture, and I offended him so badly he took his new EVA suit out through the airlock because of how much space he needed from me. But now, I'm pretty sure he's messing with me. Because I've felt him watching me for a while. I just don't know where from.

It's really quiet on the ship. I've never known Rocky to be light-footed, and it's starting to get unbearable not being able to hear him. I'm about to ask Mary to start singing for me when-

All of the lights suddenly turn off, with Mary's voice piercing through the silent darkness. "Automatic lighting disabled."

Mm no. I hate this. "Uh, no no no. Lights back on, please?"

"Automatic lighting disabled. Manual override required." Her voice is so much louder in the dark.

"Manual-" I huff. "How am I supposed to manually override if I can't see anything?"

"The manual override is located in control-"

"Yes, Mary, I know." My voice wobbles in steadily growing terror. I slowly feel my way across the dormitory before I stop suddenly in the doorway - the long, black corridor in front of me.

Rocky is in the control room. That's how he did all this fudgery with the lights. My heart picks up speed, and my nerves assure me that something (Rocky! Rocky is the only other person on this ship!) will attack if I go up there. Gulp.

I back up a bit from the doorway, turning over my options in my head - which is working in significant overtime. I feel sweaty looking down the corridor, but I refuse to take my eyes off it.

Rocky is currently in the control room, but he switched the lights off like this on purpose. He knows how useless I am in the dark. And he can see through walls, so he knows exactly where I am right now and there would be no purpose in hiding. He's probably on his way to me right now, and I'm defenseless. Unless he's already at the end of the corridor just staring at me.

I squint down the corridor. Do I see his figure at the end of it? Well, whatever I'm seeing, it looks nothing like him. Too big, too still, too wrong.

My thoughts are starting to drift into stupid territory and my mind is playing tricks on me. I try to shake it off, wiping my sweaty palms on my pants and taking deep breaths. I know he's trying to scare me, so it's stupid that it's actually working. Rocky is my best friend. He's not a monster. He'd never really hurt me-

I hear the rapid sound of footsteps charging towards me from the end of the corridor. I scream, scrambling backwards as fast as I can. It's not fast enough. A shrieking invisible thing tackles me and I brace for-

A pillow softens the blow to my head from the ground. Once all my scream putters out, I wheeze from where Rocky is squeezing me tightly.

"Wh-whhhyy.." I gasp pathetically.

"Grace get too cocky. Needed to teach a lesson," Rocky's cheery, friendly voice chirps. It does good for soothing the terror bells still ringing through my head and body. So does the squeezing. "You were sooo scared. Did not know heart can get that fast!" he sings in joy.

"Ugh, whatever! I wasn't that scared," I grunt, trying to wriggle my arms free from the death hug. I can't help the small smile that forms in my relief. "I was more afraid that you were actually mad at me."

He titters at me. "You're lying. You're scared even now. Your body-nerve-system still think I will eat you," he shimmies his carapace onto my stomach, and I grunt and tense at the nuzzling. "Maybe will. Show who is the better monster."

"Ew!" I start to laugh stupidly - the energy built up from all the terror needing to be released somehow. "No, please! At least kill me first. Or start your process over there. Away from me."

My body-nerve-system has taken over and is wiggling uncontrollably, trying to avoid his consistent nuzzling. "Pf- stop it!" I snort.

"Why, question? Thought Grace not scared." He wiggles more emphatically.

"Ah- I'm not!" My knees knock against Rocky's back as my body tries and fails to curl in, my stomach feeling more sensitive the more he moves. "I'm worried your biology is going to take over and unload on accident, thinking it's dinner time. Okay- Rhhoc- hehehe- quuuit it!" I whine, embarrassed about not being able to hold back my giggling. He's doing this on purpose.

He trills a noise of offense. "You are disgusting. That could never happen. Eridians too dignified. Ripping apart prey must always come first." He moves my arms away from my body just enough to tickle my sides and, despite expecting it, I explode.

"AGH- No! hAhahaha!!" I can never really talk when he does this. What I'm trying to say is, no! hey! get off! but unfortunately all I can manage to get out is convulsive giggling. My arms snap in over and over to protect my sides, but they're blocked by his rock hands. I only succeed in bruising myself a little.

"Don't laugh," he says while laughing himself. "encourages hungry-feeling!"

Ugh. I never win this challenge. I hold my breath, clench everything, and put every ounce of willpower I have to try and contain my giggles. Surprisingly - still squirming and with my eyes squeezed shut - I almost manage it! Until Rocky moves further up into my ribs. I whimper and fall back into hysterics.

I try to flop around to deter his hands (too many hands!!! too many hands!!) but my torso can't move at all under his FAT body. My legs are free to kick in and out as much as they want at least, but it doesn't do anything to stop him either. I can't stop it.

I continue to strain, but my head falls back in resignation as I laugh. I regret it immediately. The position turns a desperate intake of breath into the loudest snort ever. Rocky stops then, but I hardly feel relief from it - he only stopped because he's laughing at me so hard that now he can barely breathe.

"G-gett offff..." I gasp through giggles. His laughter is making him shake over my stomach again, and I'm so hypersensitive that I can't stand it. I squirm to no avail.

"♫♪what♫noise♪♫♪~~!!" He dissolves back into his amusement without finishing his sentence. I burst out into full belly laughter again despite the heat in my cheeks. His giggles are so contagious. And his vibrations are still tickling me down to the bones. I think I might die. Atleast I'm taking Rocky down with me.

Mercifully, Rocky climbs off me after a minute. His legs are weakening from laughter and he doesn't want to crush me for real. I curl up the second I'm able to in a way-too-late reaction to preserve my vital organs from tickle torture.

"I see now," he giggles. "Sensitivity is good defense. You become so funny, nothing can eat you. Predators too busy laughing."

"Please be quiet," I groan. I take a steadying breath. "Alright, I admit it. You're scarier out of the two of us. You ticked all the boxes that scare humans the most. Silence, darkness, surprise attacks. You'd definitely be able to take over humanity before I can take over Erid. Your mom would destroy me."

"No," he sighs through his vents, and I frown in confusion. Rocky's not one to reject a win. "Grace scary too. Stealth is part of Eridian nature. Know how to stay silent. Not detectable," he shudders. "You detect anyway. Almost catch me many times with crazy light detectors. Scary."

I smile incredulously. Fascinating! "So, all that just for us to tie again?"

"Grace winning for now, actually. We move ticklish from weakness to strength," I gape at him, but he cuts me off. "Serious about good defense. Funny, funny, funny."

"What- that's not- it's.." I stutter helplessly. "You're ticklish too! You know what, I'm hunting you next time."

"Grace not stealthy. Cannot ever surprise Rocky."

"Humans don't hunt our prey like that anyway. We just keep following them until they get too tired to keep running," I lean in as Rocky shies away. "We get them in their sleep, you know. When they're the most vulnerable. You might hear me coming, but you won't be able to stop me."

"♫♪!" he shakes his carapace like he's snapping himself out of it, then rushes me to start poking my sides and stomach.

"He-hey!!!" I giggle and push at him.
