Wow, nobody got the ending? Every time Cage found Rita, she said the same line, asking what he’s staring at and if she has something on her face. At the end, she jumps up excited and says something else, not wanting to sound weird if he doesn’t remember what happened. When she died, she was attacked by the Alpha and his blood must have transferred to her. She respawned before Cage could, and alerted someone, or went herself, to Paris. When he respawned, the problem had already been solved. The aliens were still alive when she respawned because all the news broadcasts are talking about how they found this “energy” in Paris and destroyed it. So Rita was able to stop it before the main battle the movie surrounded could happen.
