I honestly used to like her, she was like the comedy relief of the show, whenever something serious was going on she would be doing something funny, hilarious, etc. But as episodes went by she constantly forced Dipper to give up something for her (Example: дата With Wendy, Summer pool job, etc) but in the episode Dipper and Mabel Vs. The Future is where i Остаться в живых it. She gives away Dippers peice of the portal to Blendin (Who was possessed by Bill) and destroys it , opening the Dimensional Rift to where Bills from causing the apocalypse. How selfish of her. She does not want her brother to have a good future even though he sacrificed himself various times. How disgusting.
