Reginald

Reginald is a young man who is dating Rosanna. He has tried to propose to her in the past at least once.

History
Reginald is first seen eating at a picnic table in the beginning of "Tourist Trapped," with Rosanna sitting at the same table.

Reginald is formally introduced when he tries to propose to Rosanna in "The Legend of the Gobblewonker" while the two are "fishing" together. However, the proposal is interrupted by Stan Pines, who bothers them with his pessimistic opinions about marriage.

He and Rosanna are seen angrily leaving the re-opening of the Gravity Falls wax museum in "Headhunters."

In "The Hand That Rocks the Mabel," he and Rosanna 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. They are also seen eating at the restaurant where Gideon and Mabel are having their date.

In "The Time Traveler's Pig," Reginald and Rosanna appear in the background at the Mystery Fair. They are also seen going into the "Tunnel of Love and Corn Dogs."

In "Fight Fighters," Reginald plays pinball at the Arcade.

In "Little Dipper," Reginald can again be seen at Bud Gleeful's car dealership among several other customers, wanting to buy a car.
