I actually thought Jean did quite well here, and mostly I think she was reminding them not to underestimate this enemy who knows Krakoa better than it seems. This enemy that was able to manipulate their defences and gain entry to an island of highly powered mutants to complete an assassination mission.
I loved one other silly thing, I love how Emma and Mystique sit in their chairs. They look like the only lesbians at a meeting of straight people.
