* Trauma (9/8c NBC)
It's all fun and games until someone gets hurt. That adage holds true in this Halloween episode when a party gets out of control and the paramedics are called in. While Tyler and Boone work through the carnage, Nancy and Glenn are spooked by an unusual call. It's never a dull day on the job for these folks.
Albert Hammond Jr. performs in this week's episode, which spotlights the opening of Chuck's club in his new hotel. Needing some publicity for the event, Chuck leans on Serena and her new PR connections. Blair, meanwhile, needs to get back on Chuck's good side, so she tries to secretly help him. Elsewhere, Rufus works on getting Lily into the Halloween spirit, while Dan watches something he finds unsettling in a film - no, it's not a horror scene, but one of Olivia's on-screen sex scenes.
* Lie to Me (9/8c Fox)
Life hasn't been a bowl of cherries for Cal this season: Last week he was held hostage and tonight an old friend gets him mixed up with the mob. And then there's the Lightman Group's persistent cash-flow problem, which he caused when he bought out Zoe's share of the business to keep her (and, more importantly, Emily) from moving to Chicago. At least he has a friend in Gillian to lean on. Whether they'll ever be more than that remains an open question, but they have been friendlier lately.
* Monday Night Football (8:30/7:30c ESPN)
Philadelphia and Washington collide in what should be a contentious divisional affair after each team got in the Halloween spirit last week with frighteningly bad losses to the lowly Raiders and Chiefs. The Redskins' 2-4 start is even worse considering that Philly (3-2) is the first team they've played that has even one win. Not surprisingly, head coach Jim Zorn's job is hanging by a thread. Andy Reid's Eagles, meanwhile, are slowly seeing injury-prone running back Brian Westbrook (a D.C.-area native) get his groove back, giving QB Donovan McNabb one more reliable weapon against a tough 'Skins defense led by rookie end Brian Orakpo.
Buddy Valastro, top baker and all-around good guy, is back for another season of this tasty reality hit, which chronicles life inside his booming family-run bakery in Hoboken, N.J. In the Season 2 opener, a customer orders an engagement-ring cake, which he plans to present to his girlfriend when he proposes in the bakery. Awww, how sweet (literally)!
