Earthquake
When an earthquake hit Seattle, Ethan was in an elevator with Maggie Pierce. When the elevator stopped moving as a safety precaution, Ethan mentioned that it had happened the last time he was in an elevator during an earthquake. She was shocked as she didn't know earthquakes were a potential danger of living in Seattle. When she said she'd have to avoid being in elevators with her, he said he would just start taking the stairs.

Jean Dominy
Maggie and Ethan met again when Ethan did the films for Jean Dominy, who had a hip injury shortly after having heart surgery. After they reviewed the scans, Ethan flirted with Maggie and asked her out on a date. She declined and they had an awkward moment before he pointed out that she was in what is basically his office, so she should be the one leaving.

After the Jean Dominy case was completed, Maggie found Ethan, again in an elevator, and accepted his date. After a few minutes of awkward conversation, they agreed to have their date at the end of the week.

Maggie Pierce
He has a crush on Maggie Pierce. He asked her on a date while they worked on a case together. She initially declined, but after getting a push from a patient, she accepted his offer and they agreed to go on a date later that week.

Callie Torres
He appears to have a good professional relationship with Callie Torres. They are on a first-name basis.
