18 Year old Mabel

This is Mabel as an 18 year old to match with http://fav.me/d9509wl The idea - Dipper ends up getting stuck in the dreamworld and Bill takes him in and teaches him how to properly use magic and defend himself. I came up with the story right after the episode Ford showed up.
In the story Bill wasn't the real baddy only pretending to be to draw out the actually bad guy, who was trying to target the young twins. Bill brought Dipper to the Dreamscape to keep them safe, as long as one couldn't be touched neither could the other. So for six years Dipper stayed with Bill learning all kinds of things and Mabel stayed in the real world doing her best to keep everyone informed without letting them know it was Bill keeping Dipper safe. This picture is Mabel welcoming Dipper back after those six years have passed and Bill deemed him good enough to defend himself.
