Sarah (Lauren Graham) and Mark (Jason Ritter) fans, brace yourselves!
The Parenthood fan favorite couple is about to have a big, big fight on the NBC family drama, which is only the latest roadblock on the road to happily ever after. (Ray Romano is still proving to be a big one as well!)
However, Mark and Sarah, who recently moved in together, aren't arguing over Romano's character Hank in this exclusive sneak peek from tomorrow night's episode. No, they are arguing over Mark's role in Sarah's son Drew's (Miles Heizer) life, and his place in their family...
"I realize I don't have very much experience parenting with somebody," Sarah says after apologizing. "I want you to be involved." (We're guessing this has to do with Mark walking in on Drew and his girlfriend...in his bedroom...in a possibly compromising situation.)
Of course, Mark is very new to the whole parenting thing, saying he has no experience with any of this, but says he wanted to get closer to Drew. "I'm just trying to figure out my place in this family," he says.
So what's Sarah's response? Watch our exclusive sneak peek above to find out!
Parenthood airs Tuesday at 10 p.m. on NBC.
