Uh, please don't take this the wrong way, but if Sam gets the ATA gene and naquadah in the bloodstream, I think you're edging dangerously close to Samantha Sue territory. OTOH, something dealing with the ATA therapy and Sam, done well, would be awesome.

(We all know I love Sam, right? I mean, we're not thinking this is me pulling out some previously-hidden Sam-hating card, I hope.)
