A certain set of memories had begun flowing through Dean's mind as soon as the notion of removing pants had set in - the kind he usually tried to usher away, but at the moment he didn't seem to have the capacity for that. At least, he didn't until the word 'porno' was uttered, ripping him out of whatever thoughts he was having and throwing him into a short but hearty laugh.
"Men are never necessary in a porno," he added his two cents, grinning a bit at the idea it stirred, right up until the image of Gabriel donning a porn-stache flashed through his mind, effectively ruining whatever fantasy was taking place there.
Just in time, too, because there was apparently shit going down behind him. Without even thinking, he turned around, eyes darting for where her wound was just a few moments ago. Dean's eyes widened, not at the 'miracle' that he'd seen a million times before, but at the connection he'd made in his head. There was only one thing he'd ever seen pull off something like that.
"You're an angel," Dean announced, looking back at Emma. But, more in the 'aha, I've figured you out' kind of way, and less in the way of 'you're amazing, thank you for healing my friend' as would be the appropriate tone for those words.
