Resent photos of Asa Butterfield
Seen a lot about 12.06 & the angel blade & Cas. I just think it's interesting that for Asa & the other hunters, it's is a special object, something to be used in rare occasions & otherwise put on display and preserved. Yet Dean & Sam see angel blades as completely functional & have a few lying around. I dunno if this is a metaphor for Cas being just another tool (god I hope not - we're so past that) or just another reminder of how Cas is more human & "normal" to the Winchesters now.
