Quick and fast, but indeed nice. Even if Tony is doing something that, at most external eyes, is heroic, he doesn't see it like that. He is a good guy who started with a misstep, a troubled teenagehood that landed him in prison, but at mid-twenties he is trying to go back in track. Tony is also gay, but that is not really something that is characterizing him, it is who he is, just like if he had blue eyes, or brown hair. Sure being gay makes him the perfect match for Alec, the closeted cop who is put in charge of his security while he is the main witness on a mafia trial. Alec has always avoided temptation, but now temptation is there, at hand reach, in a very small, secluded mountain cabin.
I will not say more, just that, when it happen, it's a mix of hot and dirty, but somewhat there was also romance beneath it; Alec is like a big strong baby not realizing he can hurt people if he is not careful, but a baby isn't able to be careful, it's like emotion are boiling inside him, and then erupt, and there is not way to stop them.
