PREVIEW | Jessie Gives Tony a Very Special Gift – Debby Ryan Performs Original Song

8 pm Nikita (The CW) | This episode’s a big one: A major character dies. (Get scoop!)

8 pm Fashion Star (NBC) | The designers must interpret what a “big night out” means and design an ensemble that fits their vision. (I’m assuming there won’t be an outfit for my go-to night on the town — fro-yo for dinner followed by falling asleep watching SVU repeats — but you never know.)

8 pm Happy Endings (ABC) | Back-to-back episodes: Penny rebounds from last week’s bad news by having an affair with the Car Czar (returning guest star Rob Corddry), and Mark-Paul Gosselaar (Franklin & Bash) reprises his role as Chase, the ex-roommate whose life Max ruined.

9 pm Vegas (CBS) | Katherine arrests Dixon after Violet accuses him of assaulting her, putting Sheriff Lamb in a tough spot. Jim O’Heir (Parks and Recreation) guest-stars as a bank manager. UPDATE: A CBS news special Boston Bombers will air in place of Vegas, the network has announced.

9 pm Grimm (NBC) | Nick fights a villain who wants to turn Portland into Pompeii, and Adalind meets a mysterious gypsy in Europe. (Watch a video sneak peek.)

9 pm Da Vinci’s Demons (Starz) | Leonardo’s war designs fail, causing a rift with the Medicis. (Renewed!)

9 pm Shark Tank (ABC) | A Colorado man pitches the “perfect” English scone. (The fact that he’s from Colorado makes me skeptical, but I pride myself on giving all pastries a chance.)
