I wish they'd go ahead and solidify Jean having a part in, if not fully, creating Hope...everything is just too on the nose. And since the 90s Jean has said that to her, being Phoenix represents Hope, and as we were just reminded(well most of us Jean fans never forgot), Jean proclaimed, "I'm not going to be stand around twiddling my thumbs while our kind is totally wipe from the face of the Earth!"...so who better to have sent Hope as a way to reignite the flame that is mutantkind, than Jean.
