Either regular girls, kick-ass hunters or interesting creatures we've had plenty of portrays in the show and a lot of the time these women had affected Sam and Dean in some way yet I think a lot of them stand on their own. I've got a lot of favorites actually so I'm not including all of them in here but yeah, I think sometimes it's pretty satisfying to see these characters come by and observe the effect they had in the boys and also in the story.
So, what about you? I'm sure you have a favorite character, one that maybe you're hoping will be back sometime or maybe you just loved the way she acted and how awesome she was. C'mon, tell me! And bonus points if you include a picture :D And please (pleeeeease!!) do not bash anybody and respect each other. And have fun!
