Previous Post Patti is leaving because Barry hasn't been honest with her. Barry wants her to leave because he loves her and doesn't want Zoom or another villain to hurt her, to use their love as a weapon. So he doesn't tell her the truth. Patti finds out anyway and still leaves. Why doesn't she say, "Oh you're the Flash, I understand why you've kept that from me, you thought you were protecting me, I can take care of myself, I want to be with you despite the danger. And you can run to my new place in like 2 seconds, so why can't we still date." It just seems like by her finding out it invalidated all the convolution they had set up. PPP

She is leaving due to:

1. her life goal was to avenger her father, mission accomplished.

2. she wants to train to be CSI and not be a field detective any longer.

3. being kidnapped and nearly killed by Turtle likely helped motivate her decision

4. Barry isn't being honest with her about being the Flash

5. She has figured it out via the case files, which I suspect Barry will soon edit a bit.

6. Barry wants her to pursue her goals and not be in her way, both as boyfriend and as the Flash.

7. Barry doesn't want to put her at risk. A noble sentiment that I can agree with to an extent. By all rights though he should sever all ties to Star Labs and Joe but they are so intertwined with Barry and his activities that it would be impossible. Also ZOOM knows of Star Labs and its people already.

I would also point out that ZOOM may know of Patti and given his speed she is still likely in the crosshairs already.
