Ohhhh boy. My current prediction for the finale? Sarah and Hank get married, yadda yadda, and then we show a flash-forward to when Zeek has died and we watch them all move on from their grief. That's what I think is going to happen. And it's gonna hurt. But I'm getting ahead of myself - let's look at what happened in this episode.
Hank and Sarah are debating where they should get married. Hank wants to do something outlandish and creative, but Sarah thinks he's taking it too far. Their conversation gets interrupted when Amber feels a sharp pain, and believes she's going into labor. Sarah sends out a text to the family, and everybody rushes to the hospital. It ends up being a false alarm - gas - and so Amber has yet to give birth.
However, the gathering of the family at the hospital does have another consequence: Kristina and Jasmine get into a huge fight about the Luncheonette. When Crosby finds out that Jasmine went and talked to Adam about it, and that that's why Adam wanted to come back, Crosby angrily says that he quits. It looks like the Luncheonette will not be reopening after all. Crosby is a little angry at Jasmine for talking to Adam about things, and he says that the Luncheonette isn't special to him anymore because he can't work there with his brother as his willing and enthusiastic partner.
Chamber's Academy is having a career week, where every student gets an adviser to help them explore a passion that could turn into a career. Max is obviously working with Hank, while one of the other students wants to have Adam as his adviser. This kid wants to be a French chef! Although Adam is hesitant, because he's no expert, the two of them do manage to make a great souffle together, and all is well! Jasmine teaches some of the kids dance, and Kristina and Jasmine share a silent moment of apology for their earlier fight.
