That is so cute! Although I'd be worried about them releasing him, he seems way too domesticated. Aren't you supposed to try not to hold wild animals that much so they don't get 'humanised'?
I think that they were originally going to release him once he was hydrated etc, but then found out he's blind so decided not to. I guess being blind he wouldn't survive very long out there! So now he wil be a 'house hare'!
Bo B Bunny's Cloverbunny is a wild bunny- I believe she rescued her with a broken leg, after a dog attack I think? And she can't be released because of her leg problems either...
