I don't know Xavier said that it's harder on a telepath to defeat another telepath so i was hopeing her limited tp would be enough to let her hang in there.
The deadly thing about the Queen is her control of the inanimate.
I was hopeing that M's invulnerability would be enough and her Super strength for that.
Maybe with her superintelligence she could trick Selene into absorbing some really dieased psyic of someone that would make her rot.
