Something scandalous is headed to Castle.
Or someone scandalous, we should say, as Scandal actress Darby Stanchfield has booked a return to her fellow ABC series.
TV Guide broke the news: Stanchfield will appear as Meredith in a January episode that finds Rick Castle boxed in by the women in his life.
With Alexis falling ill just prior to her planned European vacation, Meredith will move in to Castle's apartment to care for her daughter… at the same time Beckett's apartment is being fumigated.
Sounds like Castle's biggest nightmare? Just wait until you see what happens to him on Monday's "Probable Cause."
