Woah, i really liked this episode.
Firstly David Hewlett is incredibly talented - he played Cadman so differently to McKay from her vocalisation to her mannerisms, I could believe she was a different person and not an actor playing two characters.
Zelenka's first time off world (where was he during The Storm?) was adorably cute - i love that they remember most of these characters are scientists and not trained military.
McKay's attempts at flirting were ROTFLMAO, but we knew that from before.
Yes, Ronon is the 'muscle character' but he still made me laugh - especially whilst eating and when Sheppard tried to 'teach' him about the guns. I think the reason Tyr didn't work was cos Andromeda has other 'tough' characters too so that spot's been taken. Teal'c worked cos SG1 don't - Jack may have been the military leader but he wans't ever 'muscle' and the same goes for Sheppard so I think Ronon could fit. Plus i think his relationship with Teyla could be interesting - both of them 'alien' to the rest of the Atlantis expedition, he's the last of his people, she's rarely in contact with hers and they both like playing with sticks. I still prefere Ford though.
