IM: BB 4-FB (Spymaster’s men beat up Tony Stark and inject him) takes place during IM3 8. Between pages 18-19 (after they jump him and while they’re beating him up) seems like the best spot.
The Espionage Elite don’t currently have IM: BB 4-FB in their chronologies. Number Five (“Doreen”) doesn’t appear in this scene, but the other five do.
