The movie ended with a fully-powered Carol escorting the Skrull refugees to a new home, and while we still don’t have the full scope of what she’s been doing over the last 23 years, at least it makes sense why she hasn’t been around Earth lately.
After being teased in Avengers: Infinity War’s post-credits scene when Nick Fury contacted her with his spruced-up pager before turning to dust during the Decimation, Captain Marvel officially brought Carol Danvers into the MCU fold, and we learned how she obtained her special powers and watched as she learned the secrets of her past.
