You sigh, it's one of those universes where you're really just done with everybody's shit. Instead of waking up to a brand new universe, you find yourself still with the overly annoying Mack. He's like some rip-off version of Mark but sold on craigslist for $56.74. Ok maybe that was too descriptive but still.

It's been about a month since you got here, a whole month having to deal with Mack's shit, but over the few days you noticed he acted fairly different around you, sure to others he might be bossy but to you he's more...how do you say this, quiet?. Ofcourse you brushed it off, maybe he was just having a better day than most, probably.

But really, Mack has been SO obsessed with you, he knows where you are, where you're going, who you liked and who you didn't. He thought about getting rid of everyone else so that he could have you all to himself. Oh he's REAALLY thought about it.

You've noticed that Mack's been following you more, staying by your side more and this time he doesnt talk about being the better fit captain or anything, he just...stares at you and follows you everywhere.

Now, you've had a particularly hard day today, you've been trying to find out why the 'weird stone' didn't work like it used to. Without you knowing, Mack has been watching you absolutely mesmerized about every single thing you do.

Finally, after gaining enough confidence he put up his fake facade and started walking to the very irritated captain. "You know...," he started, and even before he could add anything else, you quickly grab his arm, having a strong hold on it. "Don't."

Utterly shocked about this, Mack decided to keep his mouth shut, while also looking red. After finally having some peace, you sigh and pat him on the shoulder, seemingly not knowing you did it. Mack was over the moon, quite literally and mentally.

Squeaking, he quickly rushed to put his facade up again, but you noticed it way too late. "Poor you, flustered?." You asked with a flirty tone, you knew this would really mess with him and just wanted to play with him a bit.

Mack was a mess, he mumbled something under his breathe and quickly exited the room. You were a bit confused, but you were happy it worked. Oh, he really did think about killing everyone for a little alone time with the captain.
