Dinah spotted Dean and headed over to him, half-dragging Zee along and expecting Ollie to follow. She put an arm around Dean really briefly in an attempt to get his attention and beamed at Zatanna.
"Zatanna, this is my Dean-friend. I mean, my friend Dean," she said with a grin and then let go of Dean and gestured to Sam.
"And this is his brother Sam, who is a very good guy. I like Sam, even if I haven't gotten much chance to get to know him." She smiled at Sam.
