Relationships will be on the line on the next episode of Parenthood as Joel and Julia still struggle with their marriage and Hank and Sarah may end their friendship.

Joel is 'Not Fighting' For His Marriage

In the episode teaser for "The Offer," Julia and Joel are still dealing with the repercussions of their broken marriage. The two have been living apart ever since Julia confessed that she kissed Ed, although she said it meant nothing to her.

One of the biggest consequences is how it affects their children, who clearly aren't taking the separation well.

Mark Returns For Sarah?

"Everything was good until you got here," Sydney tells her mother in tears. "[It's] all your fault."

However, there may still be hope for the couple. Erika Christensen, who plays Julia, previously spoke with Parade magazine and said that she thinks the couple will move forward.

"They've got ten years of a loving relationship under their belts and, in the interest of their children and everything, I think they can," she said.

Sarah and Hank will also face problems of their own. While Hank attempts to be there for Sarah, she says she only wants him there as a friend and nothing more. That notion doesn't sit well with Hank.

"It's hard," he tells Sarah. "I can't be here for you anymore."

In the meantime, Camille and Zeek will get an exceptional offer on their house and it will lead to a "life-changing event."
