Robin and her mother, Genevieve, are reunited at the wedding. Marshall begins to wonder why Lily was so quick to forgive him about the secret judgeship and change her mind about Rome. Billy Zabka reveals that he saw Lily getting into the Captain's car late last night, when Lily told Marshall she was walking on the beach. Marshall becomes infuriated and, with help from the groomsmen, sets out to punch the Captain in the face. Barney joins them, despite the fact it's only three hours before his wedding. He tells Robin he'll be back in a couple hours, which is exactly what Robin's dad said to her mom right before their wedding, which Robin's mom remembers as a cute story...or, in light of their divorce, a huge red flag. Lily takes a pregnancy test (she CAN keep a secret). Daisy is the name of the daughter she's having.
