[@Lugubrious] Could you fill me in on what Laharl must have seen? Or the important stuff he is aware of?

He was present for the first part of the raid on one of the Resistance hideouts, but got annoyed and ditched rather than going underground with the others. Since then, he probably heard that the people he left managed to take down the Resistance, and that the whole this was the fault of the ringleader, who mind-controlled the others into following her orders. The following morning there was a big press release sort of thing detailing the situation to the public, right after which all the PCs (and a number of NPCs) left on the Railway Gun to head for Split Mountain. It's possible that Laharl stowed away and followed behind, which might also mean he meets Ellie, who's also following the team.
