The time when Umbra witnesses a power transfer between Nicholas and Puriel and mistakes it for them being in danger. He utters a shocked yell and douses them with water, only to be admonished by Nicholas as if he were a small child.
When Veronica kisses Umbra to make Nicholas jealous, everyone's reaction but hers is basically WTF. Although what really makes it funny is that Bezaliel, Nicholas's FATHER is snoozing on his back while the whole thing is happening.
