When Dean is on the phone with Cas in 11×04(werepire scene) you can clearly see a green pine tree hanging inside Baby. It’s right next to Dean’s knee.

OMG! Nonnie, you’re so right! Do you know what this means? 

So we have this (8×07):

This (9×06):

This (11×10):

And I had totally missed THIS (11X04)?:

Robbie Thompson gave us a line about Dean pining in 11×11, but he had already given us a PINE reference in 11×04. OK. I’m dead now. Three visual references and a verbal one. I’m good, I’m good. *hyperventilates*
