Caitlyn's certainly going to try to eke every single possible clue out of the guards and the lake and the lake monster (maybe it can secretly talk and will give them some insights? she says right before almost drowning and/or getting eaten)

Do you want me to put up a log for this? We can thread out the disappointingly fruitless interrogation or pick up later so they can search the cave and discuss or something else entirely, up to you!
