Point of no return ∞ SPN 05X18
The Song Remains the Same ∞ SPN 05X13
I almost forgot the episode that gave us Team Free Will. When Dean, with his suave approach at first, asks Cas to take them to meet mom and dad and save them from Ana. Even if Cas just told them that, that would be very, very harsh for him, besides putting them in danger. Once Dean uses this technique, he has to reach for Cas when he needs something. And once Cas is lost in those pretty green eyes, of course, he'll do whatever Dean asks of him.
Then. Cas. Literally 30 seconds later...

Finally got the time to find a scene that I like, like the framing of this two here.

BONUS:
The way Dean can't take his hands of Cas. His Cas, whom he thought he had lost to Lucifer.

The struggle in Castiel to say NO to Dean, is real. Dean focusing on Cas´s lips, like that was what was denied to him... classic Destiel. Vintage Destiel.
My Bloody Valentine ∞ SPN 05x14
Spanish version
Things that still amaze me 12 years later of this episode.
I know that the original intention about Dean staring at Cas when he finds him in front of him, was to do a bit about how clueless Castiel seems to be about the function of a cellphone. But why add the staring “straight” into the each other eyes?
The way and timing Dean saying RIGHT, just as he is apparently lost in Cas´s blues. Like the episode wasn’t titled, and at least at first about Valentine’s, couples and all about finding the Right One when it comes about love.
I suppose those first ones can be blame to Jensen’s “acting choices”?
But then, the next scene after Dean says that line, Cas holds a literal human heart on his hands, and takes his time to contemplate it. Coincidence, I presume. ¯\_(ツ)_/¯
In another occasion I will explain my theory about Cas getting infatuated by Dean only when he get to be a human in season 9. Because it was only then when he could understand and identify all about the romantic love. Against Dean already having many “feelings” about Cas ever since he had bits and pieces of memories about his own rescue from hell. Feelings that he fought hard to fade, because the pain of watching Cas die so many times. But mostly because of his constant disbelief of being worthy of the love of a celestial.
