Duo thinks Archie is kind of a moron, but he's a moron that's trying?? Which is better than he can say for a lot of people. It's important that he's a good guy, deep down, that cares about people; empathy will take you a long way in Duo's book, but he still wouldn't trust him further than to give him information that he can use to make safe choices for him and his. He thinks it's important too that Archie knows a lot of imPorts; good or bad, it means he's a networking tool, and well, information is Duo's operative biz. Archie is a good contact to stay in good graces with, despite all that.
