What should we look forward to for tonight's episode and the rest of the final season? Warning: "Parenthood" Season 6 spoilers ahead!

According to the Hollywood Reporter, "Grab the Kleenex and prepare to say farewell to the Bravermans. NBC will say goodbye to Parenthood this season with a truncated 13-episode final run that will see the Jason Katims (Friday Night Lights) series tackle subjects that the family drama has yet to explore during its five previous seasons. As Parenthood did with Kristina's breast cancer arc, one central storyline will be the driving force of season six, impacting everyone in the rapidly growing Braverman clan in different and surprising ways. The return of Breaking Bad's Betsy Brant as Hank's ex-wife will bring on a blended family story that Katims has been eager to explore. Amber's pregnancy will see kid brother Drew man up in a new way. Crosby maybe headed for a midlife crisis."

Major spoilers ahead!

The Huffington Post noted, "With Season 6 being the final season of "Parenthood," one thing's for sure: there are going to be a lot of tears. And although the "Parenthood" creators have stayed pretty quiet on some of the bigger questions, like the future of Joel and Julia, they did release a revealing trailer in August that confirmed Amber's pregnancy. Other than that, not much is known about the new season ... although series creator Jason Katims did tease something pretty upsetting. "One of the things I wanted to do with the season was to find one larger story that influences everybody on the show," Katims told TV Guide during the Television Critics Association Summer Press Tour in July. "It's a huge challenge for this family and a kind we haven't seen before ... I feel like we're going to be telling a story this year that we haven't been able to." Will one of the Bravermans die?! Only time will tell, although we're not sure our Braverman-loving hearts will be able to handle that."

It will certainly be entertaining to see Season 6 play out! Do you think it will live up to the hype of the past 5 seasons?
