Well, what just occurred while Thanatos had his Shadow hand against his face was definitely something a lot different than usual. This is the first time he's been on his knees and has had someone trip over him out of nowhere like this. He sits up a bit but only removes the hand from his face when he hears that voice -

"O-Orpheus?"

Watch as he completely ignores the fact Orpheus just tripped over him as well as ignore what it was Orpheus said out loud after said tripping over him... After all it was Orpheus. Talk about a distraction ball to stop Thanatos from crying his heart out. ... Also, he's going to be hiding his hand behind his back now. Not that Orpheus would be able to see it all zoned out like he was, anyway... Unless he could sense it, of course.
