So bruce gets de-aged (again) to when he was a kid and has no memories of his life past the age he's in which, fine, usually that would be easy to fix right, just call zatanna and let her do her thing. Except-
This happens during a very hard time in bruce's life. He had almost died a few times recently, and wasn't yet fully recovered - is one of the reasons he got de-aged in the first place, he shouldn't be on the field. And Alfred, of course, was having a low-key really bad time, worse than usual, worrying every night if that would be the night bruce would come back as a corpse.
So when bruce gets de-aged to a little kid again, Alfred can't help but think to himself, "Maybe I could do things right this time." And thus, he gets bruce and runs away with him, so that the batfam and the jl can't turn him back.
(I just think Alfred deserves to have a little crises, ok? A small breakdown, as a treat)
