So my favorite Reaper76 headcanon is that Gabriel is a HUGE NERD (which is like, strongly implied btw - http://segadores-y-soldados.tumblr.com/post/157378862270/reaper-and-soldier-american-cultural-references ).
But only Jack knows this. After being Gabriel’s “best friend” for 30-ish years, Jack knows WAY TOO WELL how nerdy Gabriel is. And he loves it of course, because Jack is just as big a nerd and he loves everything Gabriel is.
But literally no one believes Jack because “Commander Reyes is such a badass.” or “Commander Reyes is so cool.”
So Jack suffers as Gabriel blatantly drops obscure sci-fi movie references or fucking video game quotes into his everyday conversations and NO ONE GETS THEM except Jack.
Gabriel: You gotta redo this budget, Jesse - your numbers don’t make sense, Mason.
Jesse: okay, cool, I’ll do that, boss - who’s Mason?
Jack *in the background*: Someone needs to stop him.
Jesse: I dunno what ta go as for Halloween this year. Any suggestions, padre?
Gabriel: Do you like lobsters?
Jesse: I - wha
Gabriel: how do you feel about shirts with only one sleeve?
Gabriel: do you feel like the ocean’s grey waves?
Jesse: ya’ll seriously lost me like a calf in a herd
Gabriel: it’s alright, Delores - how do you feel about Paint It Black in instrumental form?
Jack: *head in hands* oh my god
Gabriel and Jack pass Winston:
Jack: Hey Winston -
Winston: Hello, commanders!
Gabriel: Sup, Rajang?
Winston: …I don’t know what that means, sir.
Jack *so mad because he gets it*: Dammit Gabriel
Gabriel: No worries, Caesar. How’s that Tesla Cannon coming along?
Gabriel and Jack debrief Genji:
Gabriel: really glad you’re going to help us out, Genji.
Genji: Thank you, sir. I will do what I can to help cut out the corruption in the Shimada clan.
Gabriel: I really respect that. So you can use a katana, shurikens, and the Sharingan?
Genji: uh, yes, the katana and shurikens, I am very proficient in. What’s a sharingan?
Gabriel: Don’t worry about it. Angela is working on new cyborg upgrades for you.
The worst moment is when Gabriel says that he “death blossomed the enemy squad” in the middle of a Blackwatch report and Jack practically starts sobbing with laughter because he knows Gabriel just dropped a fucking Last Starfighter reference and everyone else thinks Jack has lost his damn mind.
But the overall worst part is when Gabriel’s references work into Jack’s brain inadvertantly and then EVERYONE thinks Jack is a huge nerd.
Ana: Well, that mission was tough. Do you think we’ll see more from Null Sector after this?
Gabriel: *dry wheezing cackle* mierda, joder, holy shit
Jack: …WAIT SHIT NO, ANA DON’T
Ana (on the comms): Rein, Torb, you won’t believe this
Jack: I DON’T EVEN LIKE POE
Gabriel: how the fuck can you not like Poe??
Jack: Whitman is better -
Gabriel: TAKE THAT BACK RIGHT NOW
