the end is very funny!
it feels good after all this stress!
I love your description of a furious Ianto :-) and Jack subjugate and "baba" at knees before Ianto!

It's good that Jack prepares its defenses and ammunition against Hart ;

I love the way Jack helps Owen when it is afraid of the future response Tosh at his marriage request and the enthusiastic response of Tosh. It is brilliantly staged, I see very well Owen wipe disgust.

Then there was the episode Hart ... He began gently.
