Oh yes! I had wondered this thought myself when I read your previous snippets. I thought, "yes! a lifetime where they age together!" Which was VERY Rose/10.5 Dr.Who awww angsty for me. and then I thought, "but how can he be so quick to give it up? There is so much more he can do, what a help he can be!" So yay introspective angst!! Because it works so well, as much as John/Bones was indestructible and able to be faster/stronger/safer my personal canon has a lot of Jim not letting Bones do that anyway. Because Jim throws himself into danger. Indestructible best friend or not. I like a more even playing field (it allows for even more angst!) ;)
