Yes she is - that's what confuses me the most about this.

Are you sure? I've seen videos of his map just to check if I did something wrong, but in the videos Zeke recognizes Tatiana immediately and turns on Jerome. When I fight Jerome, Zeke doesn't recognize her and i'm forced to fight him and kill him. He definitely doesn't appear in the village after the fight either.

So I did everything I had to so I could get Tatiana and Zeke, but after i cleared Nuibaba's abode and recruited Tatiana, I went into Jerome's map and Zeke still fought me. As far as I know i did nothing wrong and I shouldn't have to kill him. How do I fix this?
