TV THIS WEEK: Agents of S.H.I.E.L.D. returns, new Game of Thrones, Shadowhunters series finale

If you're still reeling from the events of Avengers: Endgame, this week has you covered — Agents of S.H.I.E.L.D. is back, bringing with it a whole new world of Marvel mysteries and action.

The OG Marvel show's sixth season kicks off its 13-episode run this week, picking up after the apparent death of Agent Coulson as the team looks to rebuild S.H.I.E.L.D. and move forward in his absence. The season premiere is a wild ride, serving as a soft-reset for a new era, while also picking up the most interesting threads left dangling from last year. Oh, and of course — Evil Coulson makes his mysterious debut.

If the DC universe is more your flavor, the Arrowverse is pretty much new across the board. Arrow is bringing back Tommy Merlyn for a stint (likely as a hallucination, but hey, we'll take it), Supergirl is taking on her Russian doppelgänger, The Flash is still trying to stop Cicada 2.0, and the Legends have a rift in the team. Shadowhunters on Freeform is wrapping up with its extended series finale, Family Guy and The Simpsons wrap up their respective seasons, and (of course) Game of Thrones is all new on HBO.

Check out our full rundown of the week below, and let us know what you'll be watching.
