Also he is indeed smiling during The Wedding event. When Norris announces that they're getting married he has a big smile. Then during the wedding itself and the reception he has a look on his face of someone who is quite content and happy. Not a smile per se but he doesn't look all "grrr, eat your face" and seems quite pleased with the events.

Some people just don't show emotions. I should know: I'm one of them. At least that's what people have been telling me for years. My mother makes a joke of it at least once every time I visit my parents.
As for Connor not showing emotion when he speaks, you have to remember that his speech patterns are kind of in the extreme end of what would be considered proper speech. He doesn't use contractions, and enunciates every word. That can create a very mechanical sounding speech pattern.
There are 10 types of people in the world. Those that know binary, and those that don't. Gamertag: Talon Omega
