"Eve alway's got millions of dollars, but never gave the lone gunmen anything!!" That's not entirely true. Remember the beginning of the episode "Tango de los Pistoleros"? When Eve's yelling at them in the motel room for screwing up her mission, she gives them some money so they'll leave her alone (I think one of them proposed using some of it to go to Red Lobster). Plus, she did eventually become (More or less) friends with them.
Think of Ypres, France. Appearantly this was one of the three part whole names she came up with when trying to make feminine anagrams of Lee Harvey Oswald. She had several different anagrams of that name throughout the short run of this series. The Welsh also pronounce a Y like an I (YAN = Ian).
