The basic theme of tonight's eventful Grey's Anatomy fall finale (ABC, 9/8c) is: "You think you had a bad day?" The doctors of Seattle Grace have their hands and hearts full of trauma, with much of the chaos spinning around the emergency surgery involving Teddy's chronically ill but eternally chipper husband Henry (Scott Foley). While Teddy's up to her bloody scrubs fixing another doctor's mistake, the staff has to decide who draws the short straw to operate on the beloved of one of their own. Meanwhile, Meredith barely has time to process the latest news in her custody struggle before she and Alex are sent out in a storm to execute a delicate neo-natal transfer of a newborn that invariably hits a speed bump. The hour is classic Grey's, a multiple-hanky reminder that when it tries, this long-running medical drama can still put you on the edge of your seat and leave you wrung out when it's over.

There's a new intern helping the Jeffersonian team solve its grisly puzzles on Fox's Bones (9/8c), and he's a "simple country boy" charmer named Finn Abernathy (the likable Luke Kleintank) who disarms just about everyone — except curmudgeonly AUSA Caroline, who objects to the kid's juvie past, and Hodgins, who can't help patronizing the North Carolina boy's twangy lingo. To be fair, Finn is given to saying corny stuff like, "I'm as honest as the sunshine on the back of a honeybee." To which Hodgins retorts: "Why is that honest?" — later adding, "This is the Jeffersonian, not a fishing hole." This "Opie" is something of a savant, though, and comes in handy on this week's case, involving the death of a champion in the gut-churning world of competitive eating. (Watch out for the lurking python, by the way.) In the ongoing Bones-Booth-baby storyline, it's pretty clear Bones still has a lot to learn about the niceties of when and to whom she should share such momentous news as the baby's gender.
