In Code Green, Pam has been with Bobby, bandaging his wounds, when he states that there were forty-two people on the bus. Pam does not think that is correct and talks with Lisa, who confirms that there are forty-one patients accounted for.

In Win-Loss, Pam calls an OR for Andy. Later, Andy tells Pam if Mark's condition changes, page him.

In A Roll of the Dice, Pam greets Andy when Andy finds a navy captian's hat for him since Dr. Jordan is at a confrence meeting; Andy is covering for her. At his colluges insistance, Andy puts it on when Ryan and Pam tells him that he has a HS meeting in ten minutes, and there are three people on the phone.

Pam is talking with Jeni, a friend of Penelope's, and knows nothing about why Penelope collapsed. She says that Penelope's fiance, Jared, might know something. They had a argument earlier. David tells Pam that Penelope is out of the OR, and is stable, but she need to find some information ASAP. Peneolope is awake, and Pam is by her side, and Pam tells her that she's in Three Rivers hospital, and askes Penelope some questions.

Pam talks with Jared about Peneople's condition, and he tells Pam that he knows nothing, as they hadn't been talking. Jared confeses that he may the reason why Penelope is here, but Pam discourages this, and shares that she has been in the exact same situation, and her fiance didn't make it. David informes Pam that Peneople's insolin levels are high, and that's probally what caused her crash.
