You... Dean disappeared from the mansion, and a few days later his future self appeared. [It's a shame that the note Dean had written to himself had vanished, or Castiel would have shown that to Dean as proof. As things stand, his word is going to have to be good enough.]
He was here for a few days, over a week -- and for most of that time, he wanted nothing to do with me.
[Now he's stumbled upon information he'd thought he would keep from Dean this time around, but if he's going to explain himself properly then he needs to tell everything.] As it turns out, it's because I had died, in this future. [Not that he intends on letting that happen again. He knows the circumstances, which means he should be able to avert them. They may not be able to change the past, but they can still change the future.]
