So just why was John Locke so whack as to name his for-pay-phone-friend after his ex-girlfriend? Is it just nostalgia? Or is the man bent? Some spys in Hawaii have confided that they saw a scene being shot which appeared to be a car accident. One of the two thugs that confronted Locke about his dad in "LockDown" was on set, as well as Katey Segal who played Locke's girlfriend Helen. Ther scene definitely looked like it showed the death of Helen, and obviously the circumstances over how John Locke was paralyzed. Segal has recently joined the cast of "Boston Legal".
