Parents of the Fabulous 4

Sean
Sean has a Mother and Father and A well known Grandfather (Old Man Mgs). Sean's Parents went into hiding for an Unknown reason. It is Unknown if Old Man Mgs ever went into hiding, but if he did he has come out of it ( as seen in Episode 2). Sean's Family is known for the inheritance of Pancake Ninjas.

Trevor
Trevor has a Mother and a Father and a possible extended Family. It is Unknown if Trevor's Parents or Family went into "hiding" but considering the fact that he does not mention hiding it is probably unlikely that they did. Trevor's Family has a tradition where you must have an Animal on your head. His Family is also very big into science.
