Later that night, Julie and Susan sit in their car, watching Mike's house. Julie: "Mom, stalking? Are we really doing this? You just made such a huge deal to your friends about how much you trust [Mike] now." But that was before Susan found Mrs. Huber's journal! You see, Julie, trust is only something you have until something -- anything -- comes along to make you question it. Julie wonders what's in the journal, and Susan says, "It's not about what's in it; it's that he had it at all." Meaning Susan hasn't even bothered to read it. Even though she is a colossal snoop and the journal of a murdered woman neighbor is surely of no small interest. Then again, she managed to leave Mike's tell-all letter unsealed, so apparently she is capable of random acts of restraint. I don't see why she can't join forces with Mike: I could get behind them as a team of bumbling PIs whose investigations keep getting derailed by his accidental shootings and her endless naked pratfalls and their endless need to stop everything and start making out. Julie: "Mom, if you don't trust him, why are you moving in with him?" Exactly. Sweet Julie, you are a burning ray of reason, especially in comparison to your mother. Susan: "I don't have time to explain adult relationships to you. Oh! Duck down!" Mike is getting into his car.
Cut to Julie and Susan on the road. Julie thinks Susan's lost him, but Susan insists that Mike's just six cars ahead; if they get any closer, he'll see them. Julie points out that they can't see him either, and maybe Susan isn't so good at the art of tailing? Susan: "Oh yeah, when your father was cheating on me, I used to follow him all the time. I know my stuff." Susan? Shh! Your daughter can totally hear you! The truck turns off the road, and Susan follows it into a deserted park. Someone gets out of a car and slides into the passenger seat of the truck. Susan decides to go over there and find out what's what. Of course, she yanks open the truck door and...it isn't Mike! It's just some guy in the middle of a tryst with an ample-busted woman who's already stripped down to her bra. Wow, they sure do work fast! Susan runs off, and the woman in the bra asks the man if that was his wife. "If that was my wife," he says, "would I be here with you?" I think he's implying that Susan is more attractive than his date, which is a truly chivalrous thought, but maybe he's saying he just likes random, impulsive, paranoid women such as Susan. And is that so wrong?
