TV THIS WEEK: Wally returns on The Flash; Hobbs & Shaw; Negan helps Alpha on The Walking Dead

The Arrowverse is back in full force this week, while the newest chapter of the Fast & Furious-verse is heading to HBO for its network premiere. Oh, and LEGO Masters is looking to break some stuff.

The CW's schedule is led by the long-awaited return of Wally West on a new The Flash, while Legends of Tomorrow, Supergirl, Batwoman and Black Lightning (which is dropping its season finale!) are also all new this week. SYFY has a new episode of The Magicians and HBO has the network premiere of last year's furiously fast box office hit Fast & Furious Presents: Hobbs & Shaw. Fox's LEGO Masters is also new, with builders tasked with making the strongest bridges bricks can build.

Looking toward the weekend, Alpha and her gang of Whisperers finally strike the Hilltop, with Negan apparently helping lead the charge on The Walking Dead. There's also a sexy new Outlander on Starz, along with a heavenly fresh God Friended Me.

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