Deidara was a bit frustrated, but mostly relieved to find Zetsu. It was even better that the amnesia did seem to go away--Zetsu back to his old self would be even better. The plant shinobi was rather oddly self-conscious, which was not something he'd expected, but then again, it wasn't as if Zetsu could remember anything of what he was.

"I wonder if I could try to trigger your memory, un?" he wondered, half to himself and half to Zetsu.

He would have to be careful what he said, though. He didn't know enough about Haku to speak entirely freely, and explaining that Akatsuki was composed of S-ranked nuke-nin who were all considered dangerous criminals might not go over well.
