Grey's Anatomy

ABC | 8:00 pm

In a new Halloween episode called "Whistlin' Past the Graveyard," Alex (Justin Chambers) is feeling optimistic that he can impress investors at Pac-Gen North, until he hears decidedly unwelcome news about skeletons being unearthed at the construction site. With few other options, he asks Richard (James Pickens) to help distract the money men and women from those distasteful reports. Elsewhere, Teddy (Kim Raver) bites off more than she can chew when she tries to create original trick-or-treat costumes for kids Allison and Leo.
