I barely remember Egeria from a previous episode when I saw this. Its a foundation epiosde as tretonin is used in future episodes. Its interesting how the Pangarians used the Goa'uld regenetive powers and was able to siphon it for their own use. The science person in me wonders how such a process occur. It seems like something that would be too complicated for the general audience but still it would be interesting to find out. This is another good episode for Jonas to show off his lingual skills. He seems to be not as obsessive as Daniel. Speaking of the ruins it was so sad to see Egeria die. I think Joel (music) and the actor in question did great work in playing a somber as she dies and how the whole thing was a big mistake.
