Exclusive: Harrison Wells Has a Secret In A Clip From Tonight's The Flash

Harrison Wells is keeping something important from Barry as the two join forces in "Fast Lane," tonight's new episode of The Flash. Get a sneak peek in this exclusive clip The CW has provided ComicBook.com.

Coupled with an earlier clip that seemed to show Wells trying to covertly steal some of Barry's speed, it seems we'll start to see some serious movement on the Zoom/Wells storyline tonight.

Barry (Grant Gustin) teams up with Wells (Tom Cavanagh) to figure out a way to close the breaches, but they are distracted by a meta-human nicknamed Tar Pit (guest star Marco Grazzini) who can transform into liquid asphalt. Iris (Candice Patton) is concerned for Wally's (Keiynan Lonsdale) safety after she finds out about his drag racing hobby. When he refuses to stop she makes a bold move that puts her in danger.

Heroes Reborn actor Marco Grazzini will be appearing as Joey Montelone (aka Tar Pit), as ComicBook.com first reported.

The Flash airs Tuesday nights at 8 p.m. ET/PT on The CW.
