The Western drama Hell on Wheels returns tonight for Season 2. After Cullen's pretty epic mistake last season, we're wondering if he's going to reconsider his plan for revenge on the man who killed his family -- which, in all honesty, wouldn't be very much fun, would it? If only he wasn't living in 1865... Cullen and Emily Thorne would have had a blast conducting revenge plots together.

Hell On Wheels airs tonight at 9 PM on AMC, opposite the Season 3 finale of The Glades on A&E. Also on tonight is High School Moms -- not to be confused with MTV's Teen Mom, which is somehow very different -- airing at 8 PM on TLC. Rather check out some comedy? The premiere of NBC's new sitcom Animal Practice (yes, the show with the monkey) airs tonight at 10:30 PM. Comedy Central's Roast of Roseanne also airs tonight at 10 PM.
