Okay, the biggest question then is which direction should it go in: funny or serious? Either way could work. Actually, is it okay with you if I take a stab at writing this, since I kind of want to try it both ways?

I think it would also be cool if even Jack didn't know whether or not Sam was possessed. She could have been further away from the device/half-hidden behind something when he stepped out, so it's possible that she may have not been targeted.

Haha, I would feel bad for both the prisoner and Junior! Neither of them could possibly be enjoying that!

Also, I wanted to say that this conversation is giving me all the Stargate feels, so thank you very much for being willing to discuss all of this with me!
