Rosanna

Rosanna is Reginald's girlfriend.

History
She and Reginald are first seen eating at a picnic table in the beginning of "Tourist Trapped."

She is fully introduced when Reginald tries to propose to her in "The Legend of the Gobblewonker", while the two are boating together at Lake Gravity Falls. However, they are interrupted by Stan Pines, who bothers them with a cynical joke about marriage.

She is seen angrily leaving the re-opening of the Wax Museum of Mystery in "Headhunters."

In "The Hand That Rocks the Mabel," she and Reginald are both seen putting money into Stan's "Sack of Mystery," and then later seen walking to the Tent of Telepathy and watching Gideon's show, where Rosanna catches Gideon's cape when he throws it to the audience. This causes a minor scuffle among some of the older women. They are also seen eating at the restaurant where Gideon and Mabel Pines are having their date.

Rosanna is seen in "Irrational Treasure," watching the Pioneer Day ceremony headed by Pacifica Northwest, and cheering along with everyone else when Mabel Pines starts a patriotic chant.

In "The Time Traveler's Pig," she and Reginald attended the Mystery Fair and rode the Tunnel of Love and Corndogs.

She also attends the Sev'ral Timez concert at the Gravity Falls Civic Center and Buffet in "Boyz Crazy," hiding her eyes with sunglasses and wearing a "Sev'ral Timez" T-shirt.

In "Gideon Rises," Rosanna is among the crowd when Stan unmasks Gideon as a fraud.

In "Scary-oke," she attends the "Mystery Shack is Back" party.

Appearance
Rosanna is a thin, young, woman with light brown skin, black eyes, and long dark magenta-colored hair going down to her hips. She is usually seen wearing a magenta shirt, navy blue short shorts, and black flats.

Personality
Rosanna is deeply in love with her boyfriend and dislikes attacks on romance. She appears to enjoy fishing and, before he was revealed to be a fraud, Gideon Gleeful's performances. She is a fan of the boy band Sev'ral Timez, though she may be ashamed to admit this.
