I just wanted to touch on the calling Jean mom thing. When Nate first touched down in 616 his mind reflexively reached out to the closest thing he had to a mother and that was Jean, this thought combined with his vast power is what originally caused Maddie to form. Him calling Jean mom this time seems to be similar. He is confused and materializes again in 616 and his thoughts are on the person they were on the first time he materilized, his mother, only this time he knows who she is. Just my take
