<Snipped quote by IncredibleBee>
The fun part of roleplaying is working out why a character might do something that seems out of character. Maybe it's a chance to relax. Maybe they regard it as a duty. Maybe it's relief that things aren't more dangerous, or even simply "I'll get in trouble if I don't". The whole fun of a roleplay is not being able to predict exactly what's going to happen or why.
Yeah but like OOC there's little incentive to have your character choose a mission they don't know over an even they do know. And IC it's still a toss-up. Nobody knows what the vampire queen needs doing or how urgent it is, especially when there's already battles and stuff that might need their attention.
