And as far as I am concerned CBR/Chris Claremont screwed up
Avengers Annual 10 1981 as I recall is where Rogue depowered Carol and took her memories and personality. She then is taken by the X-men for Xavier to restore her mind. Which he did, over time, restore her memories but not emotions.
Death of Captain Marvel was published in 1982. The X-men were there but Carol wasn't.
Marvel Fanfare #24 1986 shows Claremont's weak attempt at addressing Starlin's omission. They tell Carol they tried to contact everyone he knew but couldn't reach her. She somehow missed all the broadcasts around the world and galaxy the Marv was dying.....
......on a wild guess LIKELY due to the fact that she was recovering from Rogue's attack at the time and her mind was not yet fully restored by Xavier.
Marvel fanfare's story occurs after she and the X-men return to Earth from their fight with the Brood and she becomes Binary.
The other big blunder of Claremont's attempt is that basically the X-men didn't think to tell her after she had her mind restored.
It really is odd that Starlin didn't include Carol, as a two-page weep-and-hug-fest between Carol and Mar-Vell would have fit the tone of the story perfectly.
