I’ve noticed this, too.
It’s sort of weird. Not because the Phoenix isn’t important or a big thing that shouldn’t be remembered. It is the biggest thing that has ever happened in Jean’s history.
The original animated series Phoenix never had this much of an impact though to where Jean constantly always recalled it to mind. Like, in spite of how big of an epic Jean’s time as the Phoenix was in the animated series, Jean never actually alluded to it after it happened. It makes me wonder if that means they are planning something significant with it.
Like we went from Jean talking to Charles Xavier in their fight with Shadow King,
“Professor, you taught me so much. Trust me.”
To statements from her and Madelyne going,
“I was Phoenix! Power Incarnate. The cosmos was calling to me to go and explore it.”
