However, "Expect me when you see me" is both used by G'Kar in "Chrysalis" and by Galen in two different instances in Crusade (I think "War Zone" and "Racing the Night".) The line was first used by Gandalf in Lord of the Rings.
Hardly, though that may have been the first instance you were aware of it. "Expect me when you see me" was something my mother grew up hearing and saying in the 1920's, long before "Lord of the Rings" was written. I don't have any reason to think it was new then.
