Details gathered from transcripts at Gateworld, where it's way too easy to see spoilers for much of Season 3. However, I'm not particularly sad about this.
One of the things I learned back in EFM yr 1 was that in some (ancient) cultures the practice of giving captives new names was in order to demonstrate power and control over the captives. E.g., Daniel, Hananiah, Mishael, and Azariah were assigned new names Belteshazzar, Shadrach, Meshach, and Abednigo when they were captured by Nebuchadezzar (Daniel 1:1-7).
