Any interpretations? I'd say he's remembering an old spirit similar to this one, which is shown in the fourth panel.

Venti is remembering his past. The reflection depicted Venti with his friend before Venti took on a human form (the same form as his deceased friend).

Yeah, I actually got to that poin in the game where it gets apparent on the same day (hence the deleted comment)
But thank you regardless : )
