Things get complicated when Robin gets a little too close to a patient named Stacey, who is HIV-positive and pregnant. That inspires Robin (who's also HIV-positive) to think she could be a mommy, too. Again, Patrick not on the same page. You know where this is going right?
Later in the season, Stacey is trapped in a hospital elevator with Robin's mobster ex, Jason Morgan, and his geeky sidekick, Spinelli. When Stacey goes into labor, Spinelli finds instructions for how to perform an emergency C-section on his laptop, and Jason does the surgery! Unfortunately, the procedure is too late to save Stacey and she dies, prompting Robin's decision to adopt her baby girl.
Patrick, however, isn't ready for fatherhood (we told you it was coming), which leads the couple to major dramz -- and a tearful break up by Episode Nine.
Patrick shares a rooftop kiss with the beautiful Nurse Leyla Mir, which leads to a passionate affair. They have lotsa hot hook ups, but Leyla senses that Patrick's just rebounding from Robin. She was right.
