Oh, I didn't realize... So he forgot his earlier time here. Like Brook-san.

[She's encountered this phenomenon before, but Brook is the example at the forefront of her mind, considering his return without previous memories marks the first time it had happened with anyone she was relatively close to. Vivi can't see any rhyme or reason to it--probably there is none to be found. Her smile turns a bit wistful. Though she knows it's not his fault, it hurts a little, her nakama not remembering who she is at all.] Have you seen a lot of that? Friends, or...whatever you would call Smoker-san, returning without remembering being here before?
