This is a really brief episode, and I can’t say much without a big ol’ SPOILER ALERT… Basically, I guess Abigail received John’s letter, and she’s returned with Jack to Beecher’s Hope.
There’s not a lot more happening here I’m afraid, as we just ride out to get some meat and investigate a couple of local camps. At the end we head back to see Jack, but that’s gonna kick off another part of the story, so that’s why this and the next episode are a couple of separate short ones.
