Ah yes. Indeed. As you may know, I am an enthusiastic researcher on this topic.
First let us review Jensen trying to keep Jared close during the Scooby ops outside. Jared walks away to talk to the crowd on the other side and Jensen is like WHAT. ARE. YOU. DOING. NO.

From another angle. WHY ARE YOU WALKING AWAY FROM ME, JARED?? complete with the dimples of disappointment.

Until he gives Jared one of these. That always brings Jared back:

Oh and this picture where Jared is goofing around with Scooby while looking right at Jensen and Jensen is giving Scooby a glare:

IT’S A CARTOON DOG, JENSEN.
Next up: walking through the crowd to enter the theater. Jared walking slightly ahead and Jensen with a hand on his back to guide him.

At the theater entrance- Jensen holding the door for Jared

And then the most bodyguard moment in a night full of them- Jared twirling around waving and blowing kisses at fans and Jensen literally dragging him off:

And let’s not overlook jealous!Jensen during the panel when Jensen talks about Alex being naked and Jared is WAY TOO ENTHUSIASTIC for Jensen’s liking.

Unamused.
During the red carpet interviews after the panel. Jared was blowing kisses at fans again and Jensen chooses that moment to interrupt:

Which reminded me of Jensen WHO ARE YOU KISSING Ackles at sdcc last year

That’s my dissertation on the subject of alpha/bodyguard!Jensen at PaleyFest. Honestly? I feel like you could use some of this to make a brand new fan vid for Who Watches Over Me? by nyxocity. That’s how good it is.
