Pacifica Northwest

For further information about Pacifica, you should visit the Gravity Falls wiki!
Arguably the main character of Return to the Falls, Pacifica's arc is central to the story of Summer 2013 and the adventures that she and the Pines come up against. Sarcastic, flirtatious and a reluctant investigator, Pacifica has grown from a bitter socialite to somebody with a thirst to learn about the town's history, protect her boyfriend at all costs and a mission to become just like them, while leaving her family's name and actions behind her.
=== Return to the Falls ===
Applying for a job at Greasy's Diner in September 2012, Pacifica Northwest quickly began to learn there was joy to be had in being friendly to people, and quickly became friends with Wendy, Soos, Candy and Grenda - while simultaneously getting taken under the wing of 'Lazy' Susan Wentworth, proprietor of the diner and her boss, who has become something of a surrogate mother figure - non-judgemental, kindly and accepting.
During a bakesale a few days later, she discovered Journal 3 being sold by the Oregon Forestry department, and quickly found that Dipper Pines had written about her - sparking an already reserved crush on him to grow into something more - to such an extent that she was all too eager to ask for his help and get closer to him when they returned in The Ghost of Greasy's.
Pacifica moved in with the Pines only a few days later, and very quickly went through a blazing-fast romance with Dipper, pushed almost constantly through Mabel and her matchmaking skills. Though her reservations and the loss of her luxury lifestyle have proven rather difficult, the newfound freedom of life with the Pines has made her utterly enamoured with adventure.
After standing up fiercely to her father in Big Bu$ine$$, Pacifica has developed a fierce independent streak against the Northwest Family, and dedicated herself into proving herself not only separate, but superior to her name. To all intents and purposes, she sees herself as Pacifica Pines. 
Throughout the events of Return to the Falls, Pacifica has developed more and more awareness for her family's crooked history, and has been forced to learn most of it first hand, through the events of It Came From Thrifty's, The Hunter and The Historic Horrors of Family Northwest. This has only strengthened her resolve and ill-feeling towards both her family and her surname.
Pacifica's aspirations are constantly in flux; she's yet to work out if she'd refer to stay in Gravity Falls with Susan, or joining Stan and Ford on a swashbuckling adventure across the oceans.
