“the music is in Dean’s head and Cas can hear it” is my new favorite thing and it makes an already amzing episode a hundred time better. so thx lizzy (☞ﾟ∀ﾟ)☞ (and also bless the longing retcon that makes it totally plausible i guess? the gift that keeps on giving :D)

Listen, Cas’s face doesn’t even make sense in this episode if you don’t assume that he can hear Dean’s music and he’s reacting to it with confusion and resignation that this is the man he’s fallen in love with.

It’s canon that Cas can hear music in people’s heads. He heard music in Fred’s head at the end of “ Hunteri Heroici.”  So, of course, he hears the music in Dean’s head.
