I have a pretty simple request. I want to read some fics where Dean chooses Sam over Cas. I don't mean in a sexual or romantic way. I don't want any Wincest, but they should have a strong bond as brothers. Destiel is fine, but not necessary. Basically I'm looking for fics in which Dean has to choose between Sam's safety and well-being or Cas's, and he ends up choosing Sam. I would be very grateful if any of you wonderful people could recommend any such fics for me.

Thanks in advance for your help!! :)
