One of the best shows you might not be watching comes to an end this week as Disney XD wraps up its run of the excellent Star Wars Rebels. It's never too late to catch up, but if nothing else, tune in to see how it all ends. Thankfully, another great show you might've missed is also debuting this week.

NBC's almost-canceled Timeless is back for a new season, and the premiere episode is a whole lot of fun. Along with Timeless and the final two episodes of Rebels, this week brings the 100th episode of ABC's Agents of S.H.I.E.L.D., which promises to be one of the show's biggest episodes yet. From returning characters to the details of Coulson's deal with the Ghost Rider, it's all coming out this week. The CW has a fresh slate of super stuff, led by the return of Roy Harper on Arrow and a trip into "Flashtime" on The Flash when a bomb goes off in Central City.

Looking to the weekend, there's a brand-new The Walking Dead picking up the post-Carl saga. If you're looking for something outside the airwaves (or coaxial cable), Jessica Jones Season 2 is also hitting Netflix on Thursday — just in case you don't already have enough stuff to binge.
