Parenthood's last four episodes will include some of the most emotional moments of the show ever.

Haddie Returns in Finale For Death in Braverman Family?

NBC released a nearly two-minute preview of what's to come and a big focus is Zeek's health issue.

"I've been thinking about what the doctor said about the operation. We will make the decision you and me. You with me?" Zeek asks his wife Camille.

"I'm always with you," she responds.

The whole Braverman family then gathers at the hospital as Zeek fights for his life. Things don't seem to be going well as the doctor tells him, "Your heart is just not strong."

All the hints of which member of the Braverman clan will pass away on the final season keep leading to Zeek - the father of Adam, Sarah, Crosby, and Julia.

However, the last few episodes will also hold some happy moments, including the birth of Amber's first child and Hank telling Sarah he wants to spend the rest of his life with her.

Fans will also see the anticipated reunion of Joel and Julia, who went their separate ways last season after she had an extramarital kiss.

"I will tell you this as many times as you need me to. I will never leave you again," Joel tells her.

Watch the preview below before Parenthood returns on Thursday, Jan. 8 at 10 p.m. EST on NBC.
