If Jason is Uncle Ben, then that really recontextualizes the "With Great Power, comes great Responsibility" as a barbed dig at Bruce for having all the power of Batman and as their Father, but never seem's to take responsibility for his Rogues, his Parenting, and the various bad habits that he's trained into each of his kids. It's the kind of poetic little insult that doubles as very great advice that Jason would cook up and get embroidered into a sweater that he would only wear in the safety of his safe houses.
Like, imagine all of the Uncle Ben level advice that Jason would have given to a young Peter that are all just insults to the rest of the family but also double as Really good Fucking Advice that they can't exactly Unteach him.
"When Your appearance gets you down, just remember that their is always someone who looks way more ridiculous." Is said while staring straight past Peter's head and straight at the picture of Discowing that is hidden in plain sight among his Scrapbook wall.
"Always have a backup plan, even when you think you have it in the bag" he says while thinking of the Time Babs invited Dick on a date to a restaurant that one of her regulars recommended, only to discover it wasn't wheelchair accessible when they get there.
"Rest well In the short term, so that when you have to go on those long stretches of studying, you can go that little bit farther and smarter." while remembering Tim. Just Tim. Existing.
"a well placed joke or quip can make someone's day, but remember when a situation is serious enough, to treat it seriously." remembering Steph reflexively making an ill timed joke at someone's funeral and having to apologize so fucking hard.
"Your personal interests shouldn't come second to an assignment, always take a moment to enjoy the simple pleasures." Remembering Damian in the beginning of his time as Robin trying desperately not to pet all the cats along his patrol route until one day Jason caught him in a massive pile with all the Alley Cats in a 3 mile radius in a single Alleyway. He still has the helmet footage.
"Being stealthy can help you escape bully's, but remember to stop being stealthy when among friends." Thinking back to when Cass kept accidentally scaring everyone, even Bruce, because it would appear she would pop into existence out of nowhere but had been standing there the entire time.
"Be the light that your friends can look up to, but not so bright as to overshadow their own qualities." Remembering when Duke, while still getting used to his powers while training to become the signal, had accidentally unleashed a full power light show over his entire body and had Flash banged everybody in the Batcave.
