Nanaue takes Baby back, enjoying the warm feeling he gets from holding him each and every time.

"WINGS... HEHEHE..."

This is probably a secret, but it's okay. The man seems confused and probably doesn't understand what he means.

As they turn and Michael reminds him of their actual mission (one that seems to have slipped his mind entirely) he nods, dumbly, and offers it to his brother-friend, Baby remaining cradled in the crook of his other arm.

"BAD MASK?"

That was what it was about? The details are obviously... beyond him.
