"and Ana tries to kill Fareeha" WHAT IM SORRY W H A T
That one is more of a theory on my end, as the reverse of Ana....
...would not love Fareeha, likely seeing any affection towards her as a weakness, likely lead to an attempted murder. That and if we continue with the reverse thing, Pharah would still be against Talon, specifically against Ana as the reverse of Pharah would have never wanted to follow in her mother's foot steps.
Basically MW!Ana would likely see MW!Pharah as a disappointment and a potential weakness, while MW!Pharah would just hate her mother.
