Season 3 Episode 6.... holy buckets! Twice in a Lifetime.
THAT was a real journey. I am impressed by Seth's work in this one. Even seeing Isaac in human form, yet still act and talk as usual was great.
Reminded me of Stargate Continuum, where they were told time had changed, but they refused to set it back, because the reality they had was all they'd known.... and to lose everything - they said no. And sent SG1 into different areas, telling them no communication...
Except here, it was not an option. Really felt for Gordon... To lose so much, yet never know he ever had it.
Damn.... Great episode in my opinion. I can almost do without the humour with episodes like this, but I am a sucker for Time Travel stories...
