I can't say just one people, but I'd like to. I like all of them for some thing in their personalities.
Patrick Jane is very charming, funny and clever.
Lisbon is a hard woman, that's good, I like her as the boss.
Van Pelt is a little bit naive, but nice and lovely person. I wanna know why he chose this job, it's a little weird for me.
Rigsby is a big teddy bear and Cho is always so serious, I like them, too.

Patrick Jane is my favorite, because he's so funny. "Really, it's not as bad as it looks." He's arrogant but since he really is always right I don’t mind it at all. I love Jane's contrast to Lisbon and how he knows just how to annoy her. I like Cho a lot too, since he's so serious but still comes off as funny. "I don't get zoos. You pay money to look at animals. Why?"

Jane is my favorite, he's so charming and smart, but at the same time you know there something sad about him

Cho and Lisbon...aside from Jane of course...

Of course i love Jane the most but rigsby has to be close. he is smart but goofy, never stops eating and has a crush on Van pelt who is nothing like him. i think it's cute!!
