I loved the character of Zoe. She was smart, quick on her feet and while she drove MacGyver crazy, it was educated crazy (is that even a term?) as opposed to the ditsy crazy Penny Parker or the scheming crazy Jack Dalton brought to the table. It also doesn't hurt that she's a red head.
I've always thought that of all the women Mac encountered throughout the series, Zoe should be the one he should end up with. They both have a sense of adventure and while Zoe was, "Damn the torpedoes, full speed ahead!", (to paraphrase David Glasgow Farragut), Mac balanced her out with his cautious, let's think this through mentality.
"Jeep. My Jeep? What are you talking about? Penny! My Jeep?" - MacGyver
"Look at me. I'm a hurtin' guy! I'm beat up. I need a month's worth of sleep . . . and I need a haircut!" - MacGyver
"It's been said, 'The best gift a man could ever give another, was his life', Jack Dalton was never one to settle for less than the best. Thank you Jack." - MacGyver
