Yes. It's almost hard to keep his dream self from smiling as darkly as Dean's smiling now, as he stands in Cas's room. Not yet; the dream has to stay good long enough for Dean to come forward, and instead of taking the spot Cas offers, he climbs on top of him again, straddling him as he leans in to kiss him. It's not like the others, full of heat and desperation; this one's softer, and he slides his hand around to cradle the back of Cas's neck.

He could drop the illusion now, but he wants a few seconds more, just to make sure the endgame packs as much punch as it can.
