Mitch Morgan (Zoo)
Mitch is a veterinary pathologist and animal coroner. As someone who works with animals, his high level of intelligence helps him be more intuitive because, well, it's not like his patients can tell him what's wrong.
Though he's very intelligent, Mitch tends to keep his feelings to himself. He'd be hard-pressed to find a more trustworthy person than Amy, who has two beautiful non-pierced ears ready, willing, and able to listen.
