Colby-as-Cam wasn’t meant to be quite as good as John, of course—John had to get the hero choreography, and Cam’s skills lay more in infiltration and disguise and sabotage and technological wizardry—but also wouldn’t be on the team if he couldn’t hold his own. Jason, as John, would do some protecting, some covering him, but not too much; they’d be impressively in sync, most of the fight. Lots of foreshadowing: how well they fit and flowed and trusted each other.
Colby, who’d never done action scenes on quite this scale, had been working hard with Evan to learn the choreography. He’d also practiced Cam’s knife-throwing skills and done some consulting with real hackers and retired government agents and masters of disguise, Jason knew.
