12 A Tale of Two Stans

Trapped under the Mystery Shack, Stan has to reveal his portal and his past to Dipper and Mabel, along with the secrets of his twin brother, Stanford "Ford" Pines. Stan's real name is actually Stanley Pines: thirty years ago Ford constructed the portal but got sucked inside it due to a mishap with Stanley, his estranged con-artist brother. To survive, Stanley then assumed his brother's identify as "Stanford Pines", and spent the next thirty years trying to fix the portal to get Ford back – but he wasn't able to reactivate it without the information from Ford's other two journals, until the kids recently recovered them. In the end, the agents leave after having their memories erased, and Stanford decides to live in the underground lab under the Mystery Shack. However, Grunkle Stan makes him promise he will leave the kids alone after being told that he would have to leave the Mystery Shack at the end of the summer.
