Mel catches Joe with a woman in the house in the middle of the day, someone Joe tries to pass off as a girlfriend. Mel believes him at first, asking him to be discreet with the kids, but later overhears a conversation and discovers that Joe and this woman are secretly tracking down Mel's con-man brother-in-law, and she questions Joe's motives for wanting to be her manny in the first place. Meanwhile, as Joe's been pretending to be a spy, he's totally missed the fact that Ryder seems to be slowly "losing" all of his new belongings at school.
