It is rare for Siebren to completely lose his temper. He considers himself to be a level, logical person, and anger very rarely solves anything.

Rare does not mean impossible, however; when faced with the possibility of losing a friend for good because of a poor choice, it seems anger is the go-to response.

"Do you have any idea what could have happened to you?" He's just this side of yelling; it's not often that Siebren raises his voice, but it seems today is a special occasion. "We could have lost you for good, and all because you were- annoyed?! I would ask you what you were thinking, but I do not think you were!"
