How do you "accidentally" stab someone? Don't you have to click "stab a fellow" and then click "stab that fellow over there" (which is how you arrest adventurers)? That'd be like saying "I meant to convoy to BEL, but my pen slipped and I wrote BRE! My bad; we're still friends, right?" Who was he trying to stab in Mech Alb, if he wasn't trying to stab Allison?
I accidentally stabbed a realm-member instead of the enemy--I didn't recognize his name.
