While responding to a call at the hospital, Nolan runs into Grace. They went to college together. Now she’s the Head of Emergency Medicine. It’s obvious from Grace’s reaction they had a bad breakup. Later, Nolan confides in Nick that while in college, he and Sarah hit a rough patch and broke up. He and Grace had been friends and jumped into a very hot relationship. A few weeks later, Sarah told him she was eight weeks pregnant. He still loved Sarah and immediately went back to her, got married, dropped out of school and took a job in construction.
Nick asks if Nolan would consider getting together with Grace now. Nolan says he’s involved with someone and Grace was wearing a wedding ring. He’d never do that. Nick confirms that that is the right answer.
When Grace is obviously uncomfortable around Nolan, she reminds him that she thought they were in love and he broke up with her in a note. She was crushed. Nolan apologizes. He doesn’t regret marrying Sarah and he’s loved being Henry’s dad, but Grace deserved better from him. The reason he broke up with her in a note was because he wasn’t sure he could go through with it if he saw her again. She accepts his apology.
