When William shows up at Cece's wake and announces that he's the executor of her will, the Van der Woodsen women are shocked. Even more shocking? Cece's left Ivy nearly everything of value, including Rufus and Lily's apartment.
Carol is furious and tells William that he has to fix it, or else she'll be forced to go to Lola's father for 20 years of child support. When he asks who the father is, Carol's response is a simple, pointed: "You." In other words, Lola and Serena are half sisters . . . and we thought the Charlotte Rhodes secret was messy. (And for those of you playing at home, this marks the second half-sibling that's been kept secret for most of Serena's life.)
