Whatever expression TJ is holding on her face, it's not judgment. It might be confusion, or even interest, but it's not judgment. She's read files about some of the civilizations the SGC has encountered on various planets, but nothing like this.

She's definitely not judging. She also doesn't know Jack or his idea of a very long life.
