NCIS (8:00 p.m. EST, CBS)

The NCIS crew is back! On tonight’s new episode, Tony (Michael Weatherly) and Ziva (Cote de Pablo) learn that an assassin might be on their flight as they escort a witness back from Paris. Uh oh! How will the dynamic duo handle this potentially dangerous (and even fatal) situation? Tune in to find out.

Human Target (9:00 p.m. EST, FOX)

We’re still getting to know the characters of Human Target, and tonight’s episode is sure to teach viewers everywhere a lot about Chance (Mark Valley). (No, the irony of the main character’s name is not lost on me, readers.) The leading man takes off on a wild search for the person who killed his friend, making him an unwanted guest at the Russian embassy, where he gets tangled up in even more drama including a distaff counterpart and the worldwide weapons trade.

Seems like Chance gets himself in loads of trouble, doesn’t it?

Teen Mom (10:00 p.m. EST, MTV)

Tonight’s season finale of Teen Mom is packed with loads of craziness and is, therefore, 90 minutes long. 90 whole minutes of teenage mothers who don’t know what they’re doing! Hooray! On the finale, Catelynn and Tyler continue to work on letting go of their daughter (I promise, kids, you’re making the right choice). Maci and Ryan celebrate Bentley’s first birthday together, as a family (kudos!), and Amber plans a super birthday party for her daughter.
