Grey's Anatomy season 15 episode 21 recently aired and it focused on Amelia Shepherd's story. The episode is all about who she is now and what she's done to understand what's good in her life. So, what happened in this episode?

In Grey's Anatomy season 15 episode 21, Amelia and Link traveled to New York as they needed to operate a patient who's suffering from a severe spinal deformity. This event, however, has brought a significant twist on her part. She accidentally had an encounter with her sister Nancy, and she invited them for dinner.

Amelia intentionally kept her distance, mainly because her marriage to Owen isn't smooth sailing. But since she was with Link at that time, Amelia told Nancy that Link was Owen and he is her husband. She hesitantly accepted the dinner invitation, and little did she know, her other sister - Kathleen - will be there as well.

Things get more complicated when their mother, Carolyn, shows up. It can be recalled she already met Owen when she went to Seattle to visit Derek. Amelia was surprised because she didn't know her mother was also invited on their dinner, and when she shows up, that's when she knew the trick is over.

They said Amelia is the "black sheep" of the family because she is unpredictable and she'll do things that no one else would approve. Both Nancy and Kathleen mock her and ridicule her, but when she introduced Link as Owen to them, they felt their sister had her life together and thought she ended up with a sweet guy who truly loves her.

What happened in Grey's Anatomy season 15 episode 21might not be an act for Link as well, since he proved that even after secrets were revealed, he still cares about Amelia. He was there sitting and enduring the fire they threw at her and even stood up for her. He is a great guy and what he feels towards Amelia is genuine. But how did she respond to him after the disastrous dinner?

Amelia remembered all the things she said to Link, like claiming he knew much about her life and calling him a "boy-toy" and wasn't interested with anything serious. But when she saw Link continue to stand by her even after her surgery, Amelia once again realized what she did was wrong. He's always there for her, and he truly cares, despite her messy life and family.

Meanwhile, in another part of Grey's Anatomy season 15 episode 21, Amelia had a chance to talk to her mother before she and Link departed New York. Carolyn told her she looked like her father that's why it's hard for her to show that she cares, but she cared for her daughter. The two got the closure they needed, and perhaps, Amelia will realize someday that she can talk to her mother about her troubled marriage, or even about her brain tumor.
