It's probably not how dopplegangers work. But then again, why is Caitlin so different as Killer Frost? Why does her powers make her act so much like her Earth Two counterpart down to the point of her insisting her name is Killer Frost? Her powers started developing in the months between Seasons Two and Three, which seems really suspicious. The way Team Flash discovered Cisco's powers was Harry's metahuman detector, and Caitlin's reading showed up blue. People from Earth-2 aren't affected by timeline changes in Earth-1, so I would assume that scene didn't get changed by Flashpoint. And if it did, I would wonder how Cisco's powers were discovered? Caitlin hid her metahuman abilities until the episode Shade. If she had a meta gene, Harry's watch would have detected it. Caitlin developing powers after seeing her evil self die and her split personality that acts more like Earth-Two Caitlin than Earth-One Caitlin really does support my theory.
