Avengers West Coast #100 by Roy Thomas, Dave Ross, Tim Dzon, and Bob Sharen
The death of Mockingbird was one of the earliest comics I remember reading where one of the characters died. It hit the 7 year old me pretty hard.
After Hawkeyes and Mockingbird’s divorce became final, they realized that they still loved each other and had begun to reconcile.
Avengers West Coast ended two issues later.
I’m definitely going to try and track down the gaps I have in this series.
