1) The Eyebrow lives - and sometimes says quite a bit more than the mouth ever could. *g*
2) Teal'c/Chris Judge invented "ARMS!" Apollo's only continuing the sciffy tradition. *g*
3) Teal'c is an alien. When the show gets serious about that, we get episodes like The Warrior, in which Teal'c takes things like suicide tactics in stride and the others look like they just got smacked with a very large brick - like they totally forgot the part where Teal'c grew up on a different planet and in more desperate circumstances. Of course, the alien-ness also contributes to the general sense of humor on the show - the fact that Teal'c doesn't understand American idiom AT ALL is just never going to get old for me. Teaching English to Korean teenagers has pretty much driven home just how many damn fool things we say on a day-to-day basis.
4) Three cheers for understatement! I was watching the final episode of the fifth season the other night and was genuinely impressed with Teal'c's scene with Sam. Chris doesn't get a lot of opportunity to be "out there" - the character demands some pretty severe restraint. But that doesn't mean Teal'c doesn't emote. It's all in the twitches in the face and the changes in the eyes. And I like that.
5) Teal'c has had to face some pretty severe trade-offs. He is the only member of SG1 who has a child, and he has, with difficulty, chosen to parent that child from a distance so that he may better serve his cause. Was this the right choice? Not even Teal'c knows for sure. Teal'c is also a committed patriot - yet he has been forced, repeatedly, to murder his brothers.
6) Teal'c accepted Jonas right away and fully believed in his desire to fight the Goa'uld. For all the talk about Teal'c's "Jaffa revenge thing," he can actually be very optimistic and forgiving - perhaps because he is quite aware of the darkness in his own past. Next to the atrocities he committed as First Prime of Apophis, I'm sure Teal'c considers other warriors' faults quite forgivable in comparison.
7) On the other hand, the "Jaffa revenge thing" is just cool. *g* It's part of The Mission - the thing that drives Teal'c and makes him stand out from the others. The thing that, these days, is missing in Daniel. Of course, everyone on SG1 wants to save the world, and that is a mission unto itself. But for Teal'c, it's still PERSONAL.
8) And lastly, I love Teal'c because he gets to say awesome, dramatic things like:
"Then what is the measure of a god, Gerak? Is it the scope of their power or how they choose to wield that power? Would a god who is prepared to lead us on the path of enlightenment so contradict this divine benevolence by destroying all those who refuse to believe in him?"
... and get away with it because he's a Jaffa and they all talk like that. *g*
