Honestly Gabe could get Jack to do /ANYTHING/ in exchange for unlimited access to his ass/thighs whenever he wants. He may as well not have even gotten angry about Jack being made Strike Commander, he basically owns him. Things really only start going to hell because Ana “dies” and can’t mitigate their individual asshole tendencies.

omg? I feel like a Blizzard dev has whispered the gospel of canon right into my unworthy ear.

Yeah, Gabriel is a little (a lot) miffed that little Golden Boy over there was made Strike Commander but in the end Jack comes home to worship Gabriel’s ass, and how would the higher ups feel if they knew the good, wholesome farmboy was hot for licking post-workout sweat from Gabriel’s taint and mashing his face into his armpit and getting choked by his thighs while blowing him?

but then Ana is gone and the both of them just totally implode in the worst possible ways because they loved her so much and they obvs need someone to slap them on the backs of their heads and tell them how shit is gonna get down. (and to occasionally hold their heads between her thighs and make them eat her out until her knees are wobbly)
