One of the kino webisodes does say that the people on Earth who volunteer for stone swaps actually sign forms authorizing their bodies to be used for sexual purposes. The weirdness of that aside, my main beef with the stones is that everyone was so accpeting that these strangers who walked into their houses were in fact their loved ones, and some of these people agreed to have sex with a complete stranger who just claimed to be their husband/wife/significant other. In fact, aside from Eli's mother, no one showed any real skepticism about these complete strangers claiming to be loved ones.
I knew about the kino webisode, but why wouldn't something like that have actually been in the show? I guess they wanted to have sex but not talk about the consequences.
You want consequences, what would have happened if someone got pregnant as a result of stone sex? Yes, I'm sure people took the proper precautions, but there is no such thing as perfect birth control. That would have been one hell of a mess. Bad enough if a stoned man (hah!) impregnated a woman on Earth, but even worse if a stoned woman got pregnant. All she wanted was to help two lovers reunite, now she's ended carrying a child for nine months. Who would get custody of such a child? That could have been an interesting issue to deal with.
I see the stones as a crutch and I think it would be more intense not to have them. At the same time, it does help them being able to keep in touch to keep some semblence of being part of the Stargate franchise.
Stones as they were done in Season 2 was pretty good, for the most part. As used in Season 1, I could have done without them.
