Dean did not like the sudden shift from talking to his Dad to being in the room with some people he cared a hell of a lot about, and some people who he knew he should be very, VERY scared of. His gaze caught on Ruby, and his eyes narrowed. Her. Ruby was here with all of them. Instantly Dean's mind went to ways he could hurt her, the ways he could at least send her back to hell temporarily, but he knew that with the current company, that woulnd't be a good idea.
Seeing that his Dad had his Mom safe, Dean moved in front of Claire and Ben. She had her hand over Ben's mouth, which was probably a good thing. Sam...well Sam was trained well and if anyone laid a finger on him....Dean would handle it. Dean knew there was a huge threat to his baby brother with Ruby there, but Ruby wouldn't try to bottle feed his brother demon blood with all of them there. Not if she wanted to live.
