I get what you're saying about how it could have gone down with Irina, and mostly agree with it. But I do think that the KGB knew the nostalgia factor would be strong, and that's the very reason they brought Irina back in right then.

My take on the Elizabeth-and-Gregory reunion in "Only You" is that it happened a) while Philip and Elizabeth were still broken up, and b) at a time when they both realized that Gregory only had a few hours to live. I think Philip can hardly begrudge her that, given those mitigating factors.
