It also showed that jack and Hammond could act together with the Asgard, the Nox and the Tollan in secret. No-one else picked it up. Even those who by now know them so well.
I thought it was a great act that Jack and George put on and that they could work together so well. Also, that the Asgard, the Nox and the Tollan trusted Jack and George so much.
Implies that they could ally themselves with the sgc in the future (as long as as Jack and george are around) to the possible exclusion of other parts of the government. One of my favourite episodes for all its implications.
