Well done! You captured all of their voices very well, and I loved the parts from Cas’s POV where you switched to the present tense. It gave his thoughts an immediacy, an urgency that really played up his feelings effectively.

nice, dude

This is amazing. Sometimes I think the fans forget this too... honestly, Cas' feelings are so ignored most of the time. People love him, but they don't think too hard about his heavenly family.
This was great. Keep working on the writing, you're getting better every time.
