You were Wally's kid—you can pick who the other parent is—he loved you dearly. I mean, of course he did! You were his only child! And you were perfect!
One problem... You were paralyzed from the waist down... meaning you can't move your legs... And in a family full of speedsters...that's kinda hard to deal with
You are still a speedster, you have the powers! You just...can't really use them. But you can wave your arms around really fast, does that count? You tried to push your wheelchair really fast once, but the wheelchair couldn't handle the speed and broke...so that doesn't work...
Yeah, some speedsters have problems that prevent them from using full powers, like Wally has heart problems and had a heart attack at some point. But he still uses his powers and goes super fast! But you...just can't
Right now you were chilling in your room when you dad ran in, without knocking.
Wally: "kiddo! How's it going? What are you doing? Wanna do something with your dear old dad?" He talked fast...as per usual
He liked to check up on you frequently ever since you got kidnapped by Eobard Thwane, aka reverse flash. You had been really hurt, and Wally has been protective ever since. He checks up on you like...every hour! And when he's out doing hero stuff, he makes Barry take care of you
It gets annoying sometimes...but he tries his best
He walks up to you and sits on the corner of your bed, watching you and waiting for your response
He smiles to himself, he just wants to protect you as much as he can. He failed once and he won't fail again
As long as I'm here, no one can hurt you He says to himself in his head, obviously if he told you that out loud you would say you can take care of yourself. And you can! He's just... Worried
His smile faded a little as he looked at your wheelchair...not being able to walk, run, or move your legs is basically torture for a speedster...he wishes he can just...heal you, make your legs move some how... But that's not how life works… All he can do is be here for you, and protect you
