As for the look that was passed between them when Wez nailed that geezer (Dammit, what was his name?!) to the dune buggy, that was pure "Look at me, I'm sooooo cool, impressed huh?" I hear what you're saying Humvee, and those others that think Wez's intentions were pure fatherly. But from the first moment I saw them on the big screen it was clear to me just what their relationship was exactly.
I'd heard about the Pizza delivery boy story (Lucky git for having had that chance!) and the farm scene before. To be honest I put the latter down to Vernon Wells putting a little spin on his role because it's hard to balance such a bad ass character being such a raging poofta. I find it easier if you start thinking of Wez as a Wesley. No offence intended to anyone actually named "Wesley" of course.

The "Ve ull lost somevun ve love." Seems clear to me too. In their world horror was a daily thing, everyone would have lost family and friends to that horror. Hummie was just empathising with Wez, reminding him to cool it, he ain't the only one.
