The best character scene, without a doubt, however, was when Teyla told Shep and Ronon about her pregnency. The scene suddenly rises above the rest of the episode (but not before making that awesome joke. "Don't look at me!" Oh Ronon) and gets a life of its own. Joe Flanigan was just...ridiculously brilliant in that scene, I guess, is the best way to describe it. It was just so well done. I think it was a hard scene to portray, as well. Joe had to mix into the portrayl the right amount of selfless concern for the child and Teyla, with the selfish jealousy that I read he intended to portray, which I saw as well. It must have been confusing to be blindsided like that. I think his decision, while the right one, was based on his jealously, to be honest, and he rationalised it with his concern.
Now, the best twist in the scene, is how the two men handled the news. Shep was new to all of this. He's a military guy, sure, but he's still not as laid back and mellow (yeah, I know) as Ronon is, after all his years of being hunted by the Wraith and putting up with all that crap. What this scene tells me is that Ronon is a lot more emotionally-numb than Sheppard, and that he knows that (as Sunday showed) there was nothing really there between him and Teyla. Shep, on the other hand, being a...well, guy from Earth who had to put up with much less crap and is a lot more emotionally fragile as a result (relatively speaking), probably thought there was always that possibility between him and Teyla. It was a very deep scene that can be interpreted in sooo many ways.
For me, there was definitely shipping fodder for Sheppard and Teyla, while the Ronon and Teyla interaction was purely friendship-based (but oh-so-sweet nonetheless). I might actually think about this further if I had not known that TPTB already decided that, at least for this season, there will be no real shipping.
