"Sam?"

"Yeah Gabe?"

"I need to ask for a favor."

"What is it?"

"Don't break Cas' heart, please. He's fragile and innocent and I don't want to see him go through another tough heartbreak. And... Don't ever hurt him... Please, don't."

"I swear, I won't. I love him too much to do something like that. I'd do anything to show that I love him."

"Yeah.. I know you would. Thanks, Sam."

"Of course. And don't break Dean's heart. You'll be public enemy number one if you do."

"I promise, I won't."
