"Is that really all you're worried about right now?" Them being together. He could see why Ruby was worried, but they had bigger things to deal with at the moment, didn't they? "Azazel is here, screwing around with my family, and all you can think about is whether or not we're gonna be together after you spent weeks lying to me - again?" Sam laughed incredulously, then moved over to pick up the jacket he'd slung over the back of one of the chairs at the table upon entering the kitchen earlier. "I'm going. He's a huge threat and I can't risk him hurting anyone else, let alone my family." It was a big deal to him, protecting his family. He'd lost everything. Now that he had everyone back again, Sam didn't want to lose them. He wouldn't become that bitter, cold man he had been before, drinking in the dark remains of some old, abandoned and withering house with nothing more than that numb feeling of absolute self-hatred to live off of. He wouldn't be that again. Just as Dean and Dad would never know the pains of the pit anymore, nor would Mary be ripped away from her husband and children again. And Adam, he had just gotten back from the dead. To die so quickly after having done so would have been awful.
"If I survive this thing - because yeah, Azazel is a big friggin' deal - we're gonna have a really long talk about us. This is the third time, Ruby. The third. You lying to me is the worst thing you could ever do to me." She knew that. It always led back to Lilith. The master plan. That moment on the road, where he had Ruby's own knife pointed at her throat. He had been entirely set on killing her then. But he couldn't have done. Sam didn't even think he could do it now, much as any old hunter would have screamed it was the logical decision. "I don't know if I can keep..." Now he was getting emotionally riled up and it wasn't just the anger that was to blame anymore. Frustrated, Sam slid his arms into his jacket and distractedly zipped it up. "You really let me own here, Ruby." His voice wasn't so angry on that one. Just...quiet. Defeated, almost. "I'm disappointed in you."
Sam didn't want it to end here. He didn't want this conversation to end here and he certainly didn't want their relationship to end here. But right now, he had bigger and badder problems to deal with. Sam needed to focus on that before he talked to Ruby about them.
