Mr. Rovainen

Mr. Rovainen was a researcher aboard Castle Wulfenbach, and as it turned out was possibly the worst person that could possibly have been assigned to the hive engine project. He was already enslaved, and when an Agatha Heterodyne enraged by his lechery ordered him to go do "something you should be doing", he took it as the command to go and activate the engine, killing his friend Dr. Vg in the process. He also rerouted the failsafe system so that it would kill anyone who incautiously attempted to kill the wasps.

He was among the first revenants discovered by the weasel-things, and his description of their encounter gave Baron Klaus Wulfenbach even more evidence in support of his theory that Agatha was the Other.
