Oh.

[ he tilts his head, thoughtful, ]

Well… I’m a ghost, I think? Or else I wouldn’t have been able to make it… I just remember looking for someone, and then I saw you!

But you couldn’t see me at first. So I wanted to make sure you were having fun on your big trip, before I couldn’t do that anymore.

[ then he looks at him more seriously, a little sad and a little bittersweet ]

But if I’m a ghost that must mean I died.
