From dreamers to heroes all the way to a lifelong friendship.
My headcanon for old!Hal is that he’s having a hard time letting go of his former, younger image, since he was always used to people complementing his appearance, and starts grooming himself more – shaving regularly and working out more (‘I can’t end up getting fat, Barry. My dad’s jacket is already getting tight!!’). Old!Barry on the other hand, even with his metabolism and though he eats healthy, gets a small chubby tummy because he continues eating lots of sweets. There’s just so much the speedforce can do. Unlike Hal, Barry doesn’t really mind and has accepted this change.
To no one’s surprise Hal has completely different standards for others compared to himself and finds Barry adorable with his stomach, often patting it from behind. Barry’s attempts at making Hal accept that he’s not 20 anymore usually fail. (‘Bodies change, Hal…There’s nothing wrong with that.’ ’Yeah well, easy for you to say. You look amazing.’)
