Castiel kept his eyes on Ruby for a moment longer before looking up at the arrival of the Winchester brothers, a faint frown of concern on his face at the state of Sam. Still his instinct was to use his angelic nature to make it all better again, a habit he was going to have to break out of.
"I'm sorry," He looked apologetic at bringing the brothers out, but he'd wanted to see them again as he was. And Ruby might well need them both.
"Nothing was done," he tried to smile at Ruby before stepping closer to her, cupping her face in his hands before bringing her closer for a kiss.
"You said you would still want me if I was human. I hope you meant it."
He took a deep breath and took a few steps back, offering a slight smirk at the Winchesters.
"You might want to hold her back. And look away unless you have some strange desire to have your eyes melted."
