But Stan's been a target for EVERYONE! For me this would seem like maybe the USSR lost the Cold War because they concentrated so many people on this one guy who isn't even in counterintel anymore. He's been targeted by Nina, Oleg, Philip, Elizabeth and now some whole new agent who's been so dedicated to him that she's married to him? Why isn't anyone covering Aderholt--frankly, he's the better agent. (Albeit one less vulnerable to possible flipping--though even Stan eventually proved he'd stand firm.)
