Summary:
Magic happens...
Unfortunately.
Of all the strange things to happen to their family, it was unnerving for them to find Jason transformed into an actual robin.
He apparently had some memories or at least recognition (he showed affection for Alfred, pecked at Bruce's hand, preened when Dick came by, bothered Tim on his laptop, sang for Cass and huffed at Damian). But after a while, Alfred makes them realize what it was about his transformation that was bothering them.
Although he kept looking out the windows and moved from furniture to furniture, liked it when he rode their shoulders…
He's never once tried to fly.
It's temporary...but will he fly before then?
I don't know.
