as a single dad, castiel has been through the works. so he really appreciates you babysitting for him whilst he does what he needs to do. you're special to him even if he won't admit it.

he's a sweetheart, truly, and always tries his best to be kind. even when his bluntness and straightforwardness makes him a little unappproachable. he means well.

so when he comes back from a night out whilst you were babysitting his son, he can't help but want to get to know you.
