I absolutely ADORED that flashback to Betsy's spy days in the early X-Treme X-Men, with Betsy infiltrating the Hellfire Club and ultimately getting turned away by Tessa. You could definitely see that Claremont was hinting at his plan to resurrect Betsy in her original body, showcasing she was sexy, capable and dangerous even in her early days as a STRIKE agent.
PS. I forgot to comment - unfortunately people can look amazing and still feel insecure about their appearance. Someone who works as a model and is constantly judged by the way their body looks even moreso.
