After Jacob in Wonderland, did Jacob remain with Sam and Dean until his injuries (at least the big ones) healed or did he have to make up a story for his family and friends?
Jacob had some adjusting to do before he could let himself go home. He’s learned quite a bit about hiding big secrets ever since he joined the team, but there was a lot that happened in that story. He would be way too haunted and twitchy if he went home too soon.
Luckily, they happen to know a whole village of sprites that have healing magic. Jacob was mother-henned by the Winchester brothers at the end of the story (and probably after, too), and the sprites would be no different. Especially Rischa, who knew the depth of his trauma and pain the minute he came back to the village. She wouldn’t have told the brothers since he didn’t want them to worry even more, but she’s told Bowman enough for him to be able to help Jacob out.
After he got his injuries patched up enough, he went home to try to keep himself busy, but he found himself visiting Wellwood a lot more often after Wonderland.
