Carter (Amanda Tapping) has gated out to the Prometheus, still working on getting its hyperdrive fixed (it needs lots of cool downs and can only make short jumps) as it makes its long journey back to Earth. And out there, under the command of Colonel Ronson (John Novak) they come under attack by a massive alien ship.

Grace was written by Damian Kindler this episode was first broadcast on 16 January, 2004.

In an attempt to escape the attacking ship, Prometheus heads to a nearby nebula cloud, but Carter is knocked unconscious along the way. When she wakes, she seems to be completely alone aboard the ship, and she seems to be hallucinating, as she keeps seeing a little girl, Grace (Sasha Pieterse).

She also encounters visions of her teammates offering advice in one form or another. Teal’c (Christopher Judge) warns her not to sleep, Daniel (Micheal Shanks) tells her she needs to investigate the nebula, and O’Neill (Richard Dean Anderson)…

What’s going on? Carter is determined to investigate and discover what happened to the crew and what is happening to her. She is able to figure it all out, with lots of soul-searching along the way, and it puts a but of a new light on the O’Neill-Carter potential.

I kind of like this episode; it’s very much a Carter story, and Tapping is wonderful. It also allows for a visual exploration of her character through her encounters with her hallucinations. It’s smart, emotional, and Carter is pitch perfect. And the nuance between Tapping and Anderson is so well-played.

Fallout sees the return of Jonas Quinn (Corin Nemec) with news that his home planet of Kelowna is near destruction.

Written by Paul Mullie and Joseph Mallozzi from a story by Nemec, this episode was first broadcast on 23 January, 2004.

It seems the naquadria on his planet isn’t natural. The Goa’uld who ruled the planet, Thanos (!), was able to convert the planets naquadah long ago. And now a large vein of naquadah has been discovered on the planet, and should it convert it could tear the entire planet apart.

Carter and Jonas Quinn need to figure things out. Happily, they have some of the best minds on both planets working on it.

Back at Stargate Command, Hammond (Don S. Davis) and the rest of SG-1 discover that the political parties haven’t been able to make any headway in unifying themselves or their people. And now faced with possible extinction can they find a way to work and live together?

There are twists and reveals, and the story is very much an environmental tale and about trust.

It also gives us a nice way to say goodbye to Jonas Quinn, as I think this will be his last appearance in the series.
