Sorry. I hate to spoil the twist ending for you like that, but you probably guessed Bill was never there.

[The current Dipper watches him go for a few steps before he turns to Oscar again and offers him a hand. He's going to follow that memory and Oscar can come, but he won't begrudge him hanging back if that's what he'd prefer.]
