Martha can't hook up an IV bag to Driscoll without asking him why he didn't step forward to take care of Landon when his mother died, like that's any of her business. Driscoll says he didn't find out until months after she died and Landon was already in foster care. He was trying to think of a way to approach him when Landon got in trouble of shoplifting and he saw his in. "You need to tell him," Martha urges. Driscoll refuses, saying he'd rather wait until he isn't on death's door and he's gotten Landon on "the right path" before coming clean. Martha thinks Landon needs a father more than he needs a drill instructor. Yeah, I'm sure Landon will be thrilled to find out that the man he hates is actually his father, who has apparently been deliberately absent from his life all this time. Landon really needs that.
House and Cuddy are at Waldenwood for Rachel's test playdate thing. House makes sure to wear a cap and his jacket collar way up, all the better to hide his face from that teacher when she walks by. Fortunately, a different teacher was placed in charge of Rachel, and she walks Rachel out and reports that Rachel "played with everything" and "is a very clever girl." Perhaps too clever, as the teacher wonders if an overzealous parent might have coached Rachel, since she took to the toys so quickly and even knew the name of one of them. Of course, Cuddy has no idea about any of this, and even promises the teacher that she didn't coach Rachel. Yeah, like you can believe a parent. Much to House's horror, though, Cuddy asks Rachel directly if she's ever played with any of those games before. Rachel looks at House, then says "no, Momma." House is delighted.
He runs back to PPTH and tells some random Clinic patient all about it, saying Rachel "seems so dumb" but when push came to shove, she knew to lie and lie well. The patient, who is trying to claim that he cut his leg getting into his work truck when he actually did it in his private greenhouse and was hoping, apparently, to collect some workmans comp (by going to a free clinic... ?), assumes that House is talking about his own kid, but House is quick to say she isn't, then just as quick to keep talking about how awesome Rachel is at lying. When he goes to inject the trucker with some anesthetic prior to stitching up the wound, he gets his Epiphany Face.
