It's another big departure.

Major spoilers for season 14 of Grey's Anatomy lie ahead. Again, if you're not all caught up on the recent series of Grey's Anatomy, proceed at your own risk. Grey Sloan Memorial has undoubtedly seen it’s fair share of drama over the years. But in the most recent episode, which was set to reveal what happened to Owen’s sister Megan when she was kidnapped a decade ago, there was an extra emotional moment as fans bid farewell to another doctor. Most of the episode centred around flashbacks from 10 years ago, where it was revealed that Nathan Riggs had cheated on Megan - but she also cheated on him. The flashbacks were spliced in with a present-day storyline which showed Megan, completely recovered from her risky operation, on the way to L.A. to meet Nathan after accepting his marriage proposal (again). The episode ended with Megan, Owen, and her son Farouk  playing by the water in Los Angeles. Martin Henderson, who played Nathan Riggs, joined Grey’s as a series regular in season 12 after the death of Dr Derrick ‘McDreamy’ Shepherd. This marks the fourth departure for Grey's this season. Longtime fans of the medical drama have said farewell to Dr Ben Warren, Stephanie and Eliza Minnick after the explosive season 13 finale. It was recently confirmed that One Tree Hill star Bethany Joy Lenz would be joining the halls of Grey Sloan Memorial this season. And while details of her role are being kept largely under wraps, the actress confirmed the news on Instagram last week. https://www.instagram.com/p/BawjXCmjRT2/?taken-by=joylenz She said:
