The Losers live in an Alternate Universe where most people change into animals on the night of a full moon (like, werewolves, werecats, werehawks, whatever you like). The rest of the time, they are humans but keep heightened senses and primal instincts, which is a bonus, considering their job. It's not a big deal and not something they normally talk about, but when Jensen goes into heat for the first time, it becomes a problem--it's really hard to focus on the mission when Jensen's practically panting for it without even realizing he's giving off "come fuck me" vibes. Having lusted after the hacker for years, Cougar can't take it any more; he decides to put everyone out of their misery and mates with Jensen--who becomes very enthusiastic about the idea.

Cats, man. Not to be trusted.
