Hog and Rat are the best uncles. It doesn't matter if they're not related by blood. Will be there for everything first date better believe they're your escorts, dinners they're going to be somewhere nearby, but it's not because they're worried about her safety. They are living vicariously through her current date. Seeing her grow up they can't help but feel more than a little attached.
I can totally see Hog and Junkrat being completely… just, one hundred percent conspicuous about it, even though they both wholeheartedly believe that they are being inconspicuous. They dawn some hoodies and sit on the other side of the nice restaurant wearing their hoods. Big Hog and loud ass Junkrat thinking that their niece has no idea that they’re there when she absolutely does and is used to it by now. Later she asks them if they had a good dinner, did they enjoy their food? Junkrat acts all crazy like he has no idea what she’s talking about. She stands there and listens to his bullshit, amused that he really thinks that she doesn’t know what he’s doing.
