But Derek won't be convinced. And Cristina is right, he is not the sun. Meredith is. He wanted a relationship with her even though he was still married, and for two months didn't tell Meredith. She was pissed and willing to give it a second shot, but he chose Addison. They both were civil until close to the end of S2 when he tried shaming her for sleeping with George, in which Meredith said he wasn't allowed to do that. Derek also happened to promise he wasn't going to do anything that would affect their family too much in S10, but then either forgot or drove over it, because then he decided that they were all moving to DC. Meredith was only going to go because before Cristina's last words to her, she believed there was nothing more for her to do in Seattle. But there is ALWAYS something to do there. Besides, Meredith never got the opportunity to finish her project in the 1st half of S10. Probably because the interference of Cristina's project messed hers up.
