It seems like we have a large number of characters to whom Tarvek was first introduced as a villain and who have had no time or reason to change that impression. I wonder if this is going to bite someone in the butt. Wooster would be one, especially with Gil in the book warning him specifically not to trust what he sees around Tarvek. The Jagers in general would be another group - Anevka laid it on pretty thick for the rescue team. Although Krosp and Zeetha seem to be managing - I do wonder what they think of Agatha's keeping him around, though. Even with all that time in the castle arc, there are a lot of characters who barely interacted with each other.
