She’s had a few flings since Derek died, but nothing serious has come of them, either because actors left the show or were not the right fit for Meredith Grey.
Sure, things have changed on the series since then, but it still seems a little wild to me that Meredith Grey and Andrew DeLuca would ever hook up after those events.
However, DeLuca has been a part of the series for a while and in some ways would be a good fit for a longterm romance.
Perhaps it is high time Meredith found a love interest who sticks, as well.
