He didn't have to live through it. Knowing what happened was enough. Knowing he was responsible, no matter how many times Lydia or Allison or Scott told him otherwise, was enough to make him feel it. The weight of it. The knowledge that Allison was dead back home, because she'd been trying to help save his life. But he wasn't going to focus on it right now. Not when he needed to get Scott back to Allison. They needed every single moment they could get together while they were here. That was all that mattered. It wouldn't set things right -- nothing he could say or do ever could. But at least here they had time. Even if no one knew how much time it would be.
"Yeah, I know," he said with a forced smile, patting Scott's back. "Come on, man. Let's get you back." He rubbed his neck as they started to walk. "It's been -- weird here. Without you." That was an understatement, really. It was the most time he'd ever been away from Scott since they'd met. And they'd met a long time ago. He chewed his bottom lip. Allison had been quieter than usual. Lydia, too. Part of them had just been missing since Scott vanished.
"But nothing really huge has happened. I mean, you haven't really missed anything." No. Instead, Scott had to live through Allison dying in his arms for a second time.
