I love that Dean's snark is answered with patience. Canon Dean and Sam, even when it's AU - good for you to keep them in voice. "waiting for an invite" - "no dean you idiot, I'm not sure if we're stopped on the edge of a cliff, or how far to open the door so I won't scratch your pleasant paint job."

I'm glad D. becomes a little more considerate of Sam's needs.

Did he not catch on to the brother comment in the last chapter?

Also - I would make a horrible blind person. I'd be agoraphobic shut in extraordinaire. For certain.
