This is what I think should've happened in 13x19 ending. I wish they had been more understanding of each other. Like Nathan should've understood she had to take care of her sister and Meredith should've understood the of course he will be disappointed by canceling on him.

After Meredith is left alone with her children. She doesn't think she will ever love again. But then Nathan comes along after serving in the war. And the story begins.

What happened in the plane toilet between Meredith and Riggs that Greys anatomy didn't show. I'm gonna use Riggs as that's what they normally call him not Nathan SEXUAL CONTENT
