Former "Gilmore Girls" star Kelly Bishop will check into NBC's "Mercy" later this season.
The Tony Award winner will play a patient under Sonia's (Jaime Lee Kirchner) care in several episodes of the medical drama, NBC confirms to us. The network hasn't set an airdate for the start of her arc yet.
Bishop is best known for playing the prickly Gilmore matriarch Emily on "Gilmore Girls" for seven seasons (and before that, probably for being Baby's mom in "Dirty Dancing"). More recently she's guested on episodes of "Law & Order: SVU" and "Army Wives."
