There's obviously a time between the last two panels, during which Violetta takes and closes the lantern. I think it's likely that in that time, Violetta makes very sure that her target really was Madwa and is really, truly, permanently dead. That would be a bit too gory to show.

So Violetta has just gotten enough XP to level up again! :-) She's also accomplished something truly notable in Smoke Knight society. That should be good for a couple of scoops of self-esteem.
