ending on a note

anyone else think that this ending(304) was by far the most realistic part of the show as of yet? i mean they have been playing around with the romance between Phe and Mike for a bit, but this is the first time i felt their romance would be anything like the relationship between an irish and an american spy in a similar situation might be. (the ending to season 1 was cute and all, but realistically i imagine that in the middle of a job two spys would forgo any personal matters they might have had to pursue the task at hand). especially to end the episode on it, almost to overstate the seriousness of the moment.
