User blog comment:DamiedeterJR/My Theory on Pacifica Northwest/@comment-5228195-20130323154458

maybe one of Pacificas distant relatives is blonde, or she dyed her hair. people can do that. And also Pacifica might have just gotten Waddles by a coincidence, the writers wanted to have Mabel lose Waddles and Dipper to learn a lesson about being selfless. The fact that Pacifica is from the future or something actually makes sense, Gravity Falls is filled with secrets after all.
