Things seem to be working out well for Meredith (Ellen Pompeo) and Derek Shepherd (Patrick Dempsey) on Grey's Anatomy Season 9. Derek's hand is back to normal, Meredith is pregnant, and they're suddenly multi-millionaires.

Of course, on Grey's Anatomy happiness is normally a harbinger of disaster, and Meredith's medical problems leave plenty of fans worried about her pregnancy. Are we in for more tragedy down the line?

TVLine recently spoke to Shonda Rhimes, who opened up about what's coming up for MerDer.

"Everybody thinks I kill everybody all the time," Shonda joked, adding that she likes that, because it means the audience takes "seriously" the potential threat to Meredith's health.

That said, it sounds to us like this plot is going to have a happy ending.

"We have a lovely storyline planned," Shonda said. "I think it’s going to be very beautiful for Meredith and Derek."

Shonda also noted that we'll be seeing Derek deal with feeling very responsible for "what’s happening with the hospital," and added that both Meredith and Derek are "going to be playing a larger part in the future of the hospital." And yes, that means we'll also watch "Meredith evolve as a leader and a doctor."

It sounds like we can expect good things for MerDer this year!
