Gideon Wyborn

Gideon Wyborn is a citizen of Rapture who has gone insane, possibly from splicing or the horrors of Rapture. Gideon believes that butterflies are sacred, as do most people in Rapture who seem to worship little sisters. Apparently Gieon thinks that wearing a butterfly shows support of Sofia Lamb, as it is what little sisters see fluttering around corpses (or 'angles') as they see them.
