Leo (Fallout: New Vegas)

Leo is the name of a possibly fictional character mentioned by Lily Bowen.

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. Lily also tells the courier that Leo was the one that instructed her on making the Vertibird Sword using parts scavenged from the Vertibird wreckage on Klamath back at west California.
