Yeah, 'crawler is not liable to want a part in mindcontrol. If it was ultimate nightcrawler, maybe.
I say remove the ring, unfreeze her (with Finite), and be on standby. Finite might also remove the chocolate's affects, although this is unlikely. Then, knock here out with stupefy (or put her to sleep), and tie her up with Incarcerous if she still proves affected by the chocolate. Hopefully that'll keep her pacified. If we do that, though, make sure she's out of range of plants! COMMON SENSE, people1 We don't want the crew to be eaten by getting our own looted piranha plants set on us.
Might the level of chocolate exposure also be tied into how OOC the girls are? I mean, Mercury just wanted to study, rather than joining in Kinky funtimes, and I'm pretty sure canon Peach isn't into BDSM. Amalia being out gardening might mean she's salvagable.
Keep in mind, she may still be hopping mad at us, even if we knock off the chocolate's effects. We may need diplomacy by mr. Wagner.
