Yeah, I can't possibly think of a reason why someone would yell help when they were injured and needed to get back to town to heal. Especially after being ditched in a lake.
Did it ever occur to you that perhaps, if you picked them up, and dropped them off in the town (and hey, you were at the police station, it was like a 20 second walk), maybe they would stop yelling?
Of course, I realize how much of a pain it would be to go out of your way and actually help people. Plus, everyone thinks your a b4d@55 leet haxor, it would really be cramping your style, man. I apologize, I wouldn't want to waste anymore of your precious time. Please forgive me for even suggesting it.
