Every so often, Grey鈥檚 will do a self-contained episode that鈥檚 some sort of flashback to further the story line of a character. This week, Owen鈥檚 sister Megan got the royal treatment, as some insight was finally revealed about her kidnapping and her early relationship with Riggs.

In the present, Megan and her son, Farouk, were planning to leave Seattle and move to LA to make a life for themselves with Riggs. Owen isn鈥檛 quite ready to leave his little sister after just getting her back, and is having a hard time with her leaving. So he decides to take Megan on a last-minute road trip together, so they can spend a little more time together. Turns out their relationship has always been a bit rocky, as much as they loved each other 鈥 going all the way back to the army, where they were stationed overseas.

We find out that Megan blames Owen for not sticking up for her when it came to a recommendation about a promotion, which ended up going to someone else. The thing is, Megan remembers from childhood that Owen hated road trips, so she鈥檚 a little wary of why he wants to come with her in the first place and knows he鈥檚 being overprotective. But she also knows if Owen comes, he鈥檒l feel better, and it鈥檒l help him let go of her.

Meanwhile, Riggs and Farouk are trying out the whole father-son thing in LA. It doesn鈥檛 go so well 鈥 Riggs is basically clueless about Farouk鈥檚 worries about starting a new school and living in a new place, and is kind of distracted by trying to put the house together. He thinks he鈥檚 doing an okay job of reassuring him about how he鈥檒l meet kids his own age and how things will all work out, until he ignores Farouk鈥檚 anxiousness too much and Farouk disappears.

Riggs goes frantic trying to find him, worried that he鈥檚 lost Megan鈥檚 child, and finally finds him sitting in front of a food truck. He had seen how busy Riggs was and wanted to bring him some food to help, but there were so many choices, he was stumped by what to do. He鈥檚 not used to being in a place where he had choices, and it鈥檚 too much for him. Riggs finally realizes that he needs to be more gentle with Farouk, even though what Farouk really needs is his mom.

Megan actually has a good time with Owen, until he took her to an amusement park they used to go to with their parents. It鈥檚 there Owen tries to tell her not to move, and of course, Megan blows up at that. She鈥檚 sick of Owen trying to stop her from making choices, and getting in the way of things. Owen finally admits that he did sabotage her chances of getting the promotion, something he wasn鈥檛 able to tell her before because she got kidnapped, and this just makes Megan angrier.

He had tried to stop her from getting the promotion because he thought she was being impulsive and immature, just like she was doing now by running away from her family to live on the beach. Owen really goes all out, telling her she鈥檚 also wrong to move in with Riggs when he cheated on her. But Megan points out that he鈥檚 a hypocrite, because Owen had cheated on Cristina, and then, of course, there鈥檚 always Teddy.

She also tells Owen something he doesn鈥檛 know 鈥 she cheated on Riggs first. She explains what happened before she got on the chopper, how she fought with Riggs when he asked for the ring back because she assumed he cheated on her. The real story was that Riggs had cheated too and the ring wasn鈥檛 his to give away, it was someone else鈥檚 and Megan had assumed it was hers. So Riggs had panicked and proposed. He still wanted to marry her, but Megan was so angry she told Owen just to put her on the chopper because she didn鈥檛 want to ride back with Riggs.

Megan spent a lot of time trying to figure out how to be happy, and she lost a lot of time thanks to her kidnapping, and now all she wants to do is have a life with Riggs and be happy with what she has. And this decision spurs something in Owen, who goes back and realizes that he鈥檚 not happy with Amelia in his marriage. Turns out, she feels the same way 鈥 they had both gotten married before they really knew each other, and it hadn鈥檛 been the right decision, even though they did care for each other. Poor Amelia. She really has been through hell and back these past few episodes.
