Say Good-bye to Pine Tree, Shooting Star

Nobody believes her even when she is right. When Samantha (Mabel) is at her appointment with physiologist, Matthew (Dipper,) she does something that makes him remember. What does he remember? What happened to everyone's names? What happened to Dipper? Why doesn't anyone remember a lot except for Mabel? Will I ever stop asking questions? Read to find out! Rated T for light cursing.
