Ah, an NID episode that is not only enjoyable (I usually like them!), but also manages to present the other three SG1-ers in a very favourable light, something this season has been hard pushed to do.
The doomed Barrett is great, in fact, I think I could watch quite a few eps worth of him and Sam sparring before I got bored. I think my favourite part was the ending - although I am not sure you have that time frame right Dave. Who's to say that the briefing wasn't taking place the next day? We know Kinsey was publicly 'dead' so the syndicate wouldn't have been watching for CNN to update them on whether the second attempt at execution was successful. I don't think Sam needed to do all the reprogramming in ten minutes.
I was also quite chilled by Kinsey's gratitude, it was quite satisfying overall, as when the ep began, I was thinking "No! They can't kill Kinsey, he has to be pres and create a lot more stickiness for SG1 in the future", but it was interesting that by the end the situation had come full circle, with Kinsey's future even more assured than it had already been.
I think Barratt is a shifty one, but I think and hope that this was more misdirection than anything else. When have you ever know NID men to be chat-happy, eh? I hope we see him again, but like the new tokra that was introduced a few eps ago, I hope he stays alive longer than average
