Nervous Subject (hidden)/theories

' There is also another, dead, Nervous hidden in Olive's family tree. '

Post here all your theories - be they logical or far out - as to why there are two Nervous Subjects, one dead and the other living, full of memories, as shown in SimPE.
 * I think that the memos' lie! Olive did not woohoo, but tried for baby with him!!! There!
 * I think Olive had twins and one the Beakers took and the (dead one) she kept. But the dead one accidentley died.
 * I think the developers made another Nervous, since they maybe were unhappy with the one they had. Or they fixed his face with the editing tools to refix his face. This can show up in crazy ways.
 * I think that the creators are just playing trix with us.
 * I think the Beakers performed some crazy experiment on the original Nervous and accidentally killed him. Not wanting to be the source of scandal or get arrested, Circe and Loki cloned him and no one else was the wiser.
