Emma being insecure doesn’t prove that Scott wasn’t over Jean. MJ feels insecure because of Gwen but Peter loves MJ more.
Scott can miss Jean all he wants. Just cz he moved on/loved another person doesn’t mean his history with Jean meant nothing. You ca still care about your ex-spouse without loving them romantically.
His love to Jean is more so; my first love/first wife. Legit feelings but not romantic.
Cyclops good characterisation started during/post-Morrison run. Cyclops with Jean was boring, Cyclops with Emma is a Neo-Magneto, which I approve of.
