The ultimate zombie show is just an episode away from the finale. "The Walking Dead" season 4, episode 15, the penultimate episode, features two major groups. AMC released two promo photos for the episode "Us," and they focus on Glenn Rhee (Steven Yeun) and Abraham Ford (Michael Cudlitz). The episode also has Daryl Dixon (Norman Reedus) and Joe's (Jeff Kober) group.

Glenn looks sad in the promo picture, perhaps, he is wondering where Maggie is. It has been a while, and they should unite. Will they come together in episode 15? Abraham is anyway thinking about leaving Glenn and Tara and become from five to three.

In "The Walking Dead" season 4, episode 13, Glenn was seen on the tracks looking at the Terminus map.

One of the sneak peeks for "The Walking Dead" season 4, episode 15, Abraham tells Tara that they have different missions. Abraham and company are looking for the right vehicle and then they will bid goodbyes to Glenn and Tara.

The promo shows Abraham, Eugene and Rosita in a car, perhaps they are ready to move to Washington D.C. They have a look of concern and might be worried about Glenn and Tara. In the promo, Glenn is running, and he looks scared.

He sports a great jacket and poses like a rockstar with a gun on his shoulder and water bottles tied to his waist. He is responsible for taking Eugene safely to Washington D.C. for their mission. Apparently, Eugene knows that answer to why the outbreak happened, and he wants to investigate the same in D.C.

Fans are still for Rick Grimes and other prison members to meet Abraham and hit the road to Washington D.C. However, it is unclear if this will happen in the "The Walking Dead" season 4 finale or in season 5.

Watch "The Walking Dead" season 4, episode 15 on Sunday, March 23, 2014 at 9 p.m. on AMC.
