The nightmare.

After Charlie almost getting killed, Vaggie kept getting nightmares constantly, until the rest of the hotel including Lucifer, Charlie's father, noticed their strange behaviour, and confronted them after seeing their constant panicking and Charlie flinthcing at things that she never flinched at before, let alone flinching in the first place, after debating explaining they finally caved in to the idea of telling them what's wrong, and after helping to get through everything they managed to go back to normal, like it was before the terrifying night happened, and they were greatful fot it.
