I need help finding these two fics:

1) I have read this fic a really long time ago and for the life of me, I can't remember the title or the author. So if it sounds familiar, please link me to it.
Sam and Dean are hunting a spirit. (I think its in a Museum) They have been fighting (I think...Im not so sure about this). The spirit shoots an arrow at them and Sam pushes Dean out of the way, but the arrow hits him. Then Dean asks him to sit still which he goes and gets the care and when he's back Sammy's says "You came back" or something like that.Thats all I can remember.

2) This one is set after Faith. Dean is angry with Sam for some reason. He can't believe that Sam is ok with Layla dying instead of him or something like that. And then later Sammy is seriously injured and he realizes that he would do the same for Sammy.

I know these are not very good descriptions but thats all I can remember at the moment. So if any of these ring a bell please link me to them!

Thank you!
