This One's for Gladys - S7.E9

Brian and Josh try to steer Abe away from complete isolation as Holly and Sarah try to overcome their anger at Gladys' departure. The Roadies' next clue sends them to Mexico City, where they write and perform a song with the Mexican rock band, Molotov.

After a night of drinking, Abe confesses his regrets about how he dealt with Gladys and resolves to redeem himself by trying to get her back. Meanwhile, the show must go on, and the Road Rulers take to the stage at the Hard Rock Café in front of a thousand screaming fans. With Molotov backing them, the Roadies treat the crowd to their song, ""Strangers in a Strange Land.""

The next day, Abe finds out that his efforts were in vain: Gladys will not be rejoining them. The cast is disappointed, but they realize that they need to get past everything that happened in Veracruz and move on as a group.
