John unintentionally travels back in time. Does he tell
No one, and try to fix things entirely on his own?
Sumner, because John doesn't want to get thrown in the brig?
Elizabeth, because she's the boss/John's used to working with her/other?
Ford, because Ford actually sometimes listens to John and can help him finagle things?
Rodney, because who else would he tell?
Teyla, because she's outside the system/the native guide and can help finagle where they go, and when?
Someone else? (Bates, anyone?)
No one, but things go very wrong? (Yeah, I'm not writing this one)
If someone else, who is it?
