Mark (Tyson Ritter) will reappear on Parenthood when the show returns, but it doesn't mean he will reunite with Sarah (Lauren Graham).

Joel & Julia Unhappy Living Apart?

TV Guide offered a few details on the pair's relationship and it's clear that Mark has some serious competition.

"Making things even murkier is Hank, who steps up for Sarah in a big way at the end of the season. When Amber finds out that Ryan is injured in San Diego, Hank will volunteer to drive her down there," the website explained. "A seven-hour drive has got to be worth some major brownie points, right?"

At the end of season 4, Mark's heart was broken when Sarah chose to be with Hank. Now he will appear in episode 19 airing on April 24 and he will have an unexpected encounter with another character, according to TV Line.

Another relationship in question is Julia and Joel's. Will Joel ever be able to forgive Julia for kissing Ed?

Erika Christensen, who plays Julia, recently spoke with Parade magazine about the turmoil and said she believes they can overcome it.

"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.

"It's just such an entirely new situation. Every aspect of their lives is new. Julia not working and Joel working. Victor. They're in a whole new place and they haven't had time to properly adjust to it. I think that's really what this is-their adjustment to their new situation. It's just really rough."

Parenthood returns to NBC on Feb. 27 at 10 p.m. EST.
