Till they join... lol. But on a serious note they very likely will. I see binary as a very non controversial way of marvel to give carol that most powerful avenger boost she seemingly desperately needs. Have binary collect powerful DNA all over then amalgamated the two then boom no more scarlet witch on top. People seem to hate carol but no one can hate binary she is new and a baby practically and likes cats.
The pheonix thing is something apparently my good friend Thomas bacon on screen rant strongly disagrees with.
But that's my rusted two cents.
