i’d like to see a de-aging fic where Dean and Cas revert to children because of reasons but it happens at a point in the timeline where Sam is soulless 

or it’s demon!dean stuck with little Sam and Cas

or it’s god!Cas stuck with tiny Sam and Dean …or maybe Endverse!Cas? 

do you think Cas can (or could) really turn invisible while in his human vessel for sneaking purposes (a la TMWWBK)? Just go into incognito mode and poof no one can see you?  Or is this a way of visually showing the audience that he could watch them? because if they can go invisible it would make it easy to sneak up on and stab another angel. 

why did lucifer never bother doing this? or Cas to kill lucifer (or raphael) easily? can angels still see each other even if humans can’t?
