Actually Kari and Tory were working for Jamie's M5 Industries before the show even began; Kari was in the show's pilot episode, and she and Tory were part of the behind-the-scenes support team from the beginning, although Tory didn't make his on-camera debut until the start of season 2. For me, surface beauty isn't enough without substance underneath. I mean, Jessi was nice-looking too, but didn't have the same presence or the same appeal in the ways that mattered more. She didn't project as much intelligence, grace, and wit as Kari, didn't have as good a rapport with the others, didn't have as appealing a voice or delivery, etc. (Kari's vocal delivery is terrific. Some of my most vivid memories of her are lines she's delivered in funny ways.) What makes Kari special is her substance, not just her surface (impressive though that is). And real men have no trouble seeing that.
