The missing scene between Meredith's and Nick's discussion about the job offer in the lab, and her arriving back in Seattle with him and introducing him to the kids. Meredith goes to see Nick to apologize for thinking the worst, and to explain to him why she is having a complicated time when it comes to moving. The conversation I feel the show will never give, where Meredith actually talks about DC, and how her marriage had been falling apart, for a while before her late husband died, even if they had agreed to try again.
