I agree. I don't think Aguierre was shockced at all. Who knows? He might have done the same thing at some point in his life. Still, he used it against Jack the following season.
The thing about the kiss is what made it different. Maybe Aguierre didn't see any kissing, though. We don't know that for sure. If he did, that would have given the message that this relationship went way beyond a physical release for recreational purposes only. This will always be a mystery.
I just find Aguierre to be so distasteful. The big, blustery, shit-kicker turns me off on sight, and the minute he opens his mouth, you can tell he is a know-it-all who can't be told anything. Not a very pleasant guy. Consequently, when he rejects Jack, he once again, shows his ignorance.
