Feeling the weightiness of all the implications hanging between them, Sam swallows and nods. He keeps nodding like he's considering, but there's no choice he'll make in trying to solve this that allows for Dean to be killed to resolve the issue. At least not as far as Sam's concerned. His brother's not a rabid dog meant to be taken out back and taken care of (and even if he were, Sam's not sure he'd have the ability to let anyone else carry that burden).

"We have to keep him close, yeah," Sam agrees, although his mind is still lingering on the fact that there's no proof Jack's from a future where Dean's cure comes about exactly the same way. Would they roll the dice on a hunch? They had before, but not here, where unpredictability stays Sam's hand more often than not.

He stops his pace to stand square with Jo, the severity of this situation rounding Sam's shoulders more than usual. Reaching out, he grabs both of Jo's shoulders, squeezing, holding. "We'll all go together. I've got your back," he tells her, trying so very hard to mimic how Jo appears when she's leaning on spare confidence alone to get through the day. She makes it looks easy and it's anything but.

"We'll get Cas back and we'll solve this. It's going to be fine."
