Now that Meredith and Margaret (Kelly McCreary) are on civil terms, Derek is determined to welcome his new sister-in-law into their lives — but Meredith isn't having it.
"Are you kidding me?!" Meredith snaps at her husband in our sneak peek scene. "I have to have dinner with the sister I don’t know and the bio-dad she hates because you gave up your chance to work for Obama? You're going to play that card?!"
