The Man with Two Brians
Stewie does not like New Brian. Stewie wants the first Brian to come back. Brian does not want to until New Brian is not there. Stewie goes to New Brian and tells him that he does not like him. New Brian says that he raped Rupert (Stewie's teddy bear). Stewie kills New Brian, puts him in a trash can, and writes a suicide note that looks like New Brian wrote it. The first Brian comes back to the family. Stewie is traumatized and washes Rupert in a shower.
