Good Sweeps-Week Double Ep.
25 January 2016 | by XweAponXSee all my reviews

Carter's Ascended boyfriend Orlin comes back, sort of, well... Mini Orlin.

How did we get here? Back in one of the Vala-Episodes, where she tried to recover some of her treasure from one of her former slave planets, a Prior appeared and infected them all. At the end of that episode, we thought the Prior had cured everyone.

Well, guess what, he didn't. And now, one member of an SG team returns to the embarkation room after an Ori Prior had "Blessed his Head". He's sick. Pretty soon, everyone is, even after a solid effort to quarantine everyone. So the world is on Lockdown.

But then Mini-Orlin shows up and thinks he can make a cure. But he doesn't have much time because he's not allowed to remember anything from when he was ascended and he's forgetting fast. Meanwhile, Carter and Dr. Lee had MacGuyvered a Gadget that can prevent the Ori's magic sticks from working. But only for a short time and they don't know what frequency to use. So they have to go to the Sodan Planet to test it on Cancerman (William B Davis). Gerak is trying to make the Ori Religion the Official State Religion for the Free Jaffa Nation. But he has questions, so the Ori suck him over to the Ori Galaxy and do a little Brainwashing on Spin Cycle.

With all that is happening in these 2 episodes, the main focus is Gerak, because he has to either acquit himself or become a tool to re-enslave all of his own people. It's up to Teal'c to reach him, but most of his efforts fail.

I don't know if I liked Cameron Bright ("Six" from "UltraViolet) as the post Sean Patrick Flannery Orlin, didn't seem to be the same character. In "Fragile Balance" Michael Welch did an excellent Mini-O'Neill (two LLs)- But O'Neill had been developed for years. Orlin was only in one episode... But I think the Casting department should have tried to match personalities like they did in Fragile Balance, because that kid WAS O'Neill, looked like him, talked like him, was him.

But that didn't detract from the development of story and the other characters, Cameron Bright was adequate, and in the end had an acceptable showdown with William B Davis.
