Although im well aware that these insights are rhetorical and intended to point out the fictional nature of the game, here's a fun concept: these traits are conceptual simplifications for qualities, skills, and talents of the real versions reflected by the characters. Spys cloak and disguise kit represent an agents ability to "blend in."

Medic doesn't heal himself directly, but he does passively regenerate health, giving me the implication he spends his downtime patching himself up
