Leo (Fallout: New Vegas)

Leo is the name of a possibly fictional character mentioned by Lily Bowen. It is, at this time, impossible to say whether or not Leo is imaginary, a product of Lily's Stealth Boy-induced schizophrenia, or if he is someone she actually knew once, possibly from before she was dipped in a vat of F.E.V.

As it was mentioned by Doctor Henry, Lily is mad, but not dangerous. Leo, however, is all about aggressive and sociopath behavior. When the Courier asks to Lily who is Leo she says that Leo is a very nasty person that always tells her to do bad things.
