Yes! Thank you! This is exactly how I saw it - because yes, Rodney would have done it for them, and he's come far enough along when it comes to understanding friendships that he would get this.

I also think that if Ronon had thought to ask Rodney what he wanted when Rodney was still compos mentis enough to give an answer, that Rodney would've wanted to go - not right away, but at the last minute, hell yeah, what did he have to lose? I can't believe that Rodney would reject a chance to get his brain back, even temporarily...
