Amelia Wants Her Life with Owen to Start Already

Owen brings Amelia to see the new house he bought because she was tired of his trailer. Their recent conversations about marriage, though only half-serious, are clearly on her mind. "Why aren't we doing it? Why aren't we building our life?" she asks. "I don't want to waste our time... I want a real life, and I want it with you." Owen is surprised. "Are you asking me to marry you?" he asks. "Yes!" she says, and then formally asks him.

Stephanie Doesn't Get to Say Goodbye

She broke up with him after she was barred from scrubbing in during his first surgery, but regretted her choice. When he's brought back to the hospital with worsening symptoms, they reconnect. Stephanie disagrees with the risky surgery Amelia chooses to perform, and watches the procedure from the gallery.
