No. Although I am hoping to see her in apocalypse in a flashback. In apocalypse, I hope Emma gets resurrected but it's a younger version of her to match the new Jean,Cyclops, and Storm. Hopefully a good actress for her though.
I want Fish to stay,I love the character. People say she's over the top....well there are over the top people in reality and her being a boss kind of requires her to over the top at times. I kinda think Fish will be "killed" or will "go away" for a long while and then comeback and turn everything upside down.
I just think that Magneto was kind of a link to the X-men characters for the twins. I'm also one of the ones who think the whole possible changing the twins to being inhuman has something to do with the whole x-men/fox vs. inhuman/mcu thing therefore destroying that link (magneto) will mostly cut all ties to the X-men.....just my opinion and thoughts :)
