On TV this Wednesday: Supernatural, Arrow and CSI press pause; American Idol hits its final notes and the Dunphys consider the camping life. As a supplement to TVLine’s original features, here are 10 programs to keep on your radar.
8 pm American Idol (Fox) | In the first part of Season 12’s two-night finale, Candice Glover and Kree Harrison take to the stage to battle it out one last time. (The winner will be announced Thursday night.) Also, Carly Rae Jepsen performs.
8 pm Arrow (The CW) | Season finale: As Oliver and Diggle race to stop the Dark Archer from unleashing his vengeance on The Glades, Thea inadvertently puts herself directly in the way of Malcolm’s dangerous plan. (Yep, renewed.)
8 pm The Middle (ABC) | When strangers assume Frankie is a doctor (based on her dental assistant lab coat), she goes a long way to keep up the charade. Meanwhile, Axl convinces Sue to skip class and Dr. Fulton tries to figure out why Brick doesn’t want to go to middle school. Jack McBrayer (30 Rock) and Davd Foley (NewsRadio) are back as Drs. Goodwin and Fulton, respectively.
9 pm Supernatural (The CW) | Season finale: Kevin helps Sam and Dean with a final push against Crowley; Metatron and Castiel form a plan to take on Naomi and the bureaucracy of Heaven. (Renewed.)
9 pm Law & Order: SVU (NBC) | When a comatose woman turns up in a river near the mayor’s home, the team discovers a wild side to an otherwise normal wife and mother. Richard Thomas (The Americans, The Waltons) and Kerry Butler (One Life to Life) guest-star.

Eric Roberts (Crash), James Callis (Battlestar Galactica), Tim Matheson (Hart of Dixie), Annabella Sciorra (Law & Order: Criminal Intent) and Ozzy Osbourne all guest-star. (Watch a sneak peek!) (Yep, renewed.)
10 pm Chicago Fire (NBC) | In this season’s penultimate episode, Casey is forced to work with the Intelligence Unit, which is run by a fresh-out-of-prison Voight. Awkward. Meanwhile, Mills and Dawson face some personal challenges. (Renewed… and spun-off!) (Note: A previous version of this story errantly listed this episode as the finale, per NBC’s original schedule.)
