Looks like Pietro was on the hunt for a new piece of booty to hump, and boy did he find one.
Frisca was in the wrong place at the wrong time, seperated from her team after a monster house she ran and got lost deeper into the dungeon.
One thing led to another and BAM she fell right into Pietro's trap, right before she could use a rollcall orb to.
And it doesn't look like he has any intention to let her go soon XP
