Cool obervation!
I do enjoy spotting Jensen or Dean things in Jason, and there are plenty. The way he flirts, the way he looks at guys all wide eyed and... um... I guess like he wants their approval, maybe, the way he tilts his head disarmingly, the angry somewhat protective glare, even the way he says "I don't know" and the way he gives Lana the flowers - just shoves them at her like Castiel's coat...
I love Dean!
