At some point in time the whole doctor/river arc will have to end or loop around, right? But what if we have an awesome spin off like the Sarah Jane Adventures and see all the crazy stuff River and 11 got up to like Jim the Fish etc etc. Ofc, that's if Moffat hasn't got a elaborate and cunning plan up his sleeves, which he probably does... Ramble Ramble!
Oh god, don’t give me hope like that! It would be awesome, at least a few episodes =D But yeah, I definitely think that won’t happen… Oh you’re so cruel, why do you said that to me?! =’( Now I want it! ;)
