Brutus was First Seen in the Gosa Mob as a subordinate adult male. The dominant female was Cleopatra and the dominant male was Gandalf. It is unknown if Brutus is related to either of them. The Gosa seemed to have suffered a large group split leaving just ten members. The pregnant dominant female Cleo gave birth, but her pups did not survive. This tragic event caused the Gosa to split up. Brutus joined a half led by Cleopatra's pregnant younger sister Delilah. However, the two halves rejoined quickly. After Delilah gave birth Cleopatra made the gang move burrows, resulting in Delilah's pups being abandoned. Because of this, Delilah made the Gosa split up again. Brutus joined Delilah's half once more and attempted to mate with her, but was refused. The two halves eventually reunited again.
