I love how it appears that Tommy is the grounded, well-adjusted foil to Buck's devil-may-care adrenaline junkie, but I also have to remind myself that Tommy was the guy who was asked to steal a helicopter and fly it into a category 5 hurricane on a hunch, and he was like, "yeah, cool, let's go."
Buck probably thinks Tommy's a rational, responsible adult, because he's so considerate and he owns a house and he's so methodical when he takes Buck apart in bed and he's got a 401k and a Roth IRA account. The helicopter heist flight was definitely an outlier.
But eventually he learns the truth: Tommy's batshit insane.
Like, they're hanging in bed one morning and Buck's on his phone trying to solve the math riddle Hen sent him, and he laments the loss of his lightning-enhanced skills. And Tommy, turning the page on the WWI biography he's reading, absently says, "At least you got them. All I got was 30% hearing loss in my left ear."
Buck slowly lowers his phone and demands an explanation, and Tommy, still focused on his book, tells him about when he was struck by lightning. Both times. The second time he was in the middle of a hoist and winch rescue trying to get to the captain of a sunk fishing boat in the middle of open ocean during a storm. Tommy holds his place in his book with his thumb and shows Buck the picture Lucy took of his Lichtenberg burn—it spans the entirety of his back and goes halfway down his arms. Buck stares at it, stunned, then takes the phone and book out of Tommy's hands, tosses them on the floor, and proceeds to suck Tommy's brain out through his dick.
The first time Buck goes to see Tommy at Harbor, Tommy is still en route back from a call, so Buck gets to talking to two people named Nico and Dana who've worked with Tommy since he arrived. Buck sheepishly apologizes for putting Tommy in such a dangerous position with the hurricane.
Nico and Dana look at each other and snort. Nico puts his hand on Buck's shoulder and is like, "Dude, that is not the craziest thing Kinard's ever done. That's not the craziest thing he's done this year."
They tell him about his legendary but batshit NATOPS check maneuvers and how no one's ever been able to figure out how he can do a barrel roll in low altitude in a transport bird.
They tell him about the time he and Donato were called to a high-rise gas explosion, and they casevac'd an unconscious, pregnant woman who ended up going into labor. Tommy got back there and, with the power of WikiHow on his side, delivered a healthy baby girl halfway to LA General.
They tell him about the time he sustained a concussion while landing a malfunctioning helicopter in the baseball field of a middle school, and yet somehow found the strength to host an impromptu AMA to three hundred kids about what being a pilot's like while he munched on tater tots and waited for a rescue.
They tell him about the time he was flying with a probie at night in an area with uncharted power lines that got tangled in the rotor, and how he slung the probie under his arm like a tote bag and dove out of the helicopter right before it exploded.
They tell him about the time Tommy and Nico were called to a cliffside mansion where some foreign dignitary's daughter was being held hostage. Tommy ended up HRSTing out of the helicopter and onto the scene, and then proceeded to beat the hell out of the guy, get himself stabbed, and give the SWAT team so much shit when they arrived that the 217 has an honorary table every year at the Backdraft Ball.
When Tommy finally shows up and disembarks, Dana's halfway through a story about the time they were all called to Shasta County to help with the Carr Fire in 2018, and as soon as Buck sees him over Dana's shoulder, he shouts, "You flew into a fire tornado?!"
Tommy's expression goes a little hunted and he holds up his hands placatingly, like, "In my defense, I tried to find another way around it—"
And Dana's like, "The fuck you did. You looked me dead in the eye and said, 'You know what would be funny?' And then you banked right into the whirl."
"It's not like you tried to stop me," Tommy says accusingly, ignoring the way the side of his head is starting to smoke from the intensity of Buck's stare.
"Well, no, you were right: it was funny," Dana says with a shrug.
That night, Buck rides Tommy slow and vicious and makes him recount every detail of the fire whirl flight before he'll let Tommy come, and the entire time he grips Tommy's head and forces him to hold Buck's gaze and thinks, I can't believe I ever thought you were normal. You're insane, you're out of your mind, you're perfect, you're perfect, you're perfect for me.
In the afterglow, practically humming with satisfaction, Buck bites playfully at Tommy's chest and says, "So this is what Lucy meant when she texted me that you and I match each other's crazy. Hell, after everything you've done, I think the only thing left to check off your list is, like, aliens."
And Tommy's entire body freezes and he falls very silent very suddenly. Buck lifts his head to stare at him, like, "You've gotta be kidding me."
"Evan, for legal reasons, I need you to change the subject."
