So, for a start, we have only Michael almost and after the theft in Section, he is sent to Prague to get get back the files what contains information about every operative in Section. They win the bidding but get the files back isn't so easy. We do have some stylish moments on Prague - like Michael who looks so sincere when he thanks the opposite bidder for returning the head of one of their agents.
So, we get back .. where ever normally they are, just to let the stoler assassinated. The probability stays that he might met someone in bus, so they go trough the people there and Gray Wellman is the possible person, who might have the files now - so Nikita is brought in and as most of the times, she, again, get emotionally involved, start to care and then fall in with the guy.
But all this should be on background as the files are important - that leads Nikita in dangerous situation as she gets dangerous necklace (I adored the scene where she gets back to Section and how easily she manages to give information without telling it and the way the play that conversation). She goes back and they stage her explosion, to get Benko. Nikita has to put herself into the risk, of course, and for moment give us the feel that maybe Benko thinks about pushing that button - but we all know he won't. So she has the button and for a moment, she almost gives it to Michael - but no.. she still holds it for herself. Very symbloic.
I also most say that scene on the middle of the episode, when she mets Benko's agent and he tooks his weapon out - and as always - Michael just has to be near. It was quite sweet. Plus I liked the ending - why he was there, we can not know sure, but he is keeping his eyes on her.
