Secrets are coming out at this little shindig and with this family, that's going to be a messy, uncomfortable, but entertaining thing. For once, Callie might actually manage to be out of any and all drama that goes down at the party. She's happy and in love. Go, Callie!

The Foster family keeps getting bigger and messier. It extends far and wide, and that's one of the beautiful things about it. Anyone and everyone can be a Foster! Mike is happy to make a new family of his own with Ana, baby Isabella, Ana's family, and of course AJ.

Stef is thankful that Jesus has such a strong-willed girlfriend who won't marry him on the whim. Emmas has handled Jesus' TBI better than what's expected of a young girl who has been through a lot. Stef takes a moment to acknowledge that.

Maybe it's the happy occasion, the fact that they're kind of sort of, possibly going to be family now, or the fact that they genuinely seem to be doing better apart, but the tension and awkwardness between Callie and AJ doesn't last too long.

It has to be an awkward situation for someone like Gabe. He's at his ex-girlfriend's engagement party, at his biological kids' parents' house that he's crashing at, with his ex's parents who hate him there. Not a fun position for anyone. Gabe is a trooper.

Lena and AJ have never spent very much time around one another. They are an unlikely duo to be mingling at the engagement party. What could they possibly have to talk about together? Whatever it is, it may have caught Emma's attention.

Stef is not only proud that Brandon (with the help of Mariana, of course) put together such a fantastic engagement party for Ana and Mike, but she's happy that her ex-husband and best friend has finally found happiness.

It's back-to-back grandparents on The Fosters. This time, the twins get to spend some time with their biological grandparents/Ana's parents. There's more than enough love to go around at this unusual family affair.

Stef as nothing but a warm embrace for Emma. Despite the tension between Emma and Mariana, and the awkwardness between Emma and Jesus after his "proposal" Emma shows up to the party to support the family that always welcomed her.

Callie and AJ left things on a sour note the last time they spent time together. Callie got her feelings off her chest regarding AJ cheating on her. AJ called Callie out on part of the downfall to their relationship. Will they be able to move past that and be cordial?

Ana's parents greet the happy bride-to- be warmly. They have not had very much time to know Mike, but they must approve of her new fiance and this new, healthy stage in Ana's life. They must be proud.

Stef and Lena steal a moment to themselves. With so much going on with their family, all of the time, they occasionally need to take a beat and just breathe. Plus, consuming a little coffee. The secret to running a family as chaotic as the Fosters is lots of caffeine.
