Yep, I love me some Pissy!Mac.:drool::drool: There's also a great Pissy!Mac scene at the end of Officer Blue when he tells the cop killer he should be put to death - 'No trial, no jury, eye for an eye'. Then there's the scene at the end of Tanglewood with Sonny Sassone when he says 'I'm a Marine, you little punk. I've put men in the ground in foreign soil so you can sleep at night. But you wouldn't know anything about that, would you, kid?'. Also there's the one at the end of Til Death Do We Part when he gets all pissy with the undertaker guy who was selling those clothes poisoned with formaldehyde off the corpses. And also at the end of Sweet 16 when he tells the abusive stepdad/killer guy he'd give a year's pay for two minutes alone with him. And the scene with Hawkes in Murder Sings the Blues.:drool::drool::drool:
I love Pissy!Mac not just 'cause he's hot, but also because we really get to see him show some emotion, and because he isn't pissy in every episode (he doesn't react as emotionally to everything as Danny does) that when he does get all pissy you can't help sit up and take notice. I also think that Mac getting pissy proves that he's anything but cold. Cold people don't get pissy - because IMO if you get pissy with a suspect that means you're really emotionally affected by whatever crime they've committed.
But I also like when Mac's all gentle and soft with a victim or a member of his team - like the woman in Night, Mother, the boy in Sweet 16, the woman in Blink, Stella in All Access, Danny in RSRD, and that woman in Open and Shut. *swoon* He can be so sweet sometimes, and so pissy/scary at others. And he's always hot, of course.
