I agree! Wilt's other sides of anger and fear are really interesting. I could watch the "Hum-na" reaction over and over again!
It's kind of refreshing to see him get a little upset because it means he is standing up for himself for once. Granted, while in Bus The Two of Us, he still manages to mix in apologies with the stern talking-to he gives Mac, he still nonetheless stands his ground and tells them what's up and how uncomfortable they are making him by making him lie.
He deserves to stand up for himself every now and then!
