"And once again you stand before me, claiming you know what's best for everyone. A new day, but the same old tune, Sam," Castiel actually rolled his eyes. "Have you learned nothing yet?"
Why was he defending Ruby so much, after she'd betrayed him so thoroughly? Castiel wasn't even sure he knew why, just that this, the easy option, it wasn't the answer.
"You don't get to take the easy road on this, killing her won't make the problems all go away."
Despite everything, despite the fact that this human in front of him had been having an affair with his girlfriend, Castiel actually felt sorry for him.
"Have you thought to actually ask them if they want you? Talked to them maybe? Or are you just assuming how they'll all react to you?" Castiel glared at him. "Go and talk with your family, Sam. Ask their forgiveness and accept their help. Talk to your girlfriend. You may find out you have more left than you think."
