Her death allowed the whole team to finally get some down time. Rufus asked Jiya to move in with him, in an actual home, and Lucy and Wyatt finally got together officially, with no dead secretly evil wives to get in the way. 

The mothership was immediately destroyed, but Agent Christopher saved the lifeboat, just in case. 

Cut to 4 years later, in 2023. Lucy's teaching an American history course about only women in history, and she and Wyatt have two adorable twin girls named Flynn and Amy. 

Jiya and Rufus started Riya Inudstries and did well enough that Jiya was signing autographs for young kid scientists, and they all got back together one last time to take the lifeboat out once again for one last mission, back to 2014 to visit Flynn in a bar in Brazil to make sure everything happened the way it was supposed to. 

It worked, and to celebrate, we got a montage of lots of kissing, which was great.
