Nervous Subject (hidden)

This Nervous Subject is hidden in Olive's family tree. This is the Nervous that Olive remembers giving birth to. He is unplayable. It is also unknown if the Grim Reaper is his father because Olive (and all of her family) has dark skin while Nervous' is light and the Grim Reaper has no genetics. He can be found using SimPE and he will have a second thumbnail in the Elder Stage hidden in his character files. Why it's there is unknown, but there is a strong possibility that it's the playable Nervous Subject's father's thumbnail.
