In the first new clip from the next episode of "The Flash," Barry undercuts Harrison Wells' argument that it would take too long for the young hero to get up to speed on Earth-2 science by utilizing his powers for some serious speed-reading.
In the second clip, Iris decides to "bond" with Wally, and shows up at one of her young brother's illegal street races.
FAST LANE: Barry teams up with Wells 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 is concerned for Wally's 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.
The "Fast Lane" episode of "The Flash" airs tonight at 8 PM ET on the CW.
