A solid Cameron-centric stand alone episode, not something we've seen so far and shockingly it's a decent, fairly intelligent little episode.
The premise is a bit of an SF cliche - a chair that can be used to add or remove memories. Cameron 'remembers' killing the woman he hit on the previous night, but this is SG1 after all, we know Cameron hasn't done it. Thankfully the episode sorts this out quickly and it isn't about proving his innocence which would have been really tiresome, but finding out who did.
The show includes a few good twists and Ben Browder gets a chance to show he wasn't just brought on board to look nice and be a replacement O'Neill. The script isn't as good as what he got to work with on Farscape, but he does the best with what he has to work with.
