This season of "Grey's Anatomy" will be one for the books: ABC has ordered an additional three episodes of the series, bringing its total season 15 episode count to a whopping 25 installments.
According to TVLine, that's tied for the second-most episodes ever aired during a season of "Grey's," following season three (which also clocked in at 25 episodes) and season two (which aired a jaw-dropping 27 installments). And the demand for so much "Grey's" is definitely still there, with the long-running series currently holding the title of ABC's most-watched program -- a distinction it also enjoyed back in season 14, too.
The Ellen Pompeo drama shows no signs of slowing down, and will soon cross yet another major milestone off its bucket list: It is set to air its 332nd episode later this season, surpassing ER's record as the longest-running medical drama in TV history. TVLine reports that that episode will feature a unique, winking twist: It won't have any medical storylines.
The site adds that that gimmick may tie into the introduction of a multi-episode arc featuring Jennifer Grey. Though no details have been revealed about Grey's "Grey's" character just yet, she's rumored to be playing the mother of Jo (Camilla Luddington).
Sounds like there's plenty for fans to look forward to in the coming months. "Grey's Anatomy" returns from its midseason hiatus on January 17.
