Spending a night in the cave wasn't as bad as Jack initially thought. He realised he had spent a lot of his time in dark places and caves ever since being with Ray. It never seemed to bother him as much as the others, but now when he thought about it, it made sense.
The town where he grew up was underground after all, so it was a no brainer that he never felt fear or anxiety when going underground. Furthermore, the children tried to make Jack's stay as comfortable as possible.
The kids shared a bed while allowing Jack to have a whole bed to himself. He felt a little awkward, but due to his size, there was really no other choice. It didn't take long though for Jack to fall into a deep sleep.
He didn't even know when it had happened, it just did.
He was far too worn out about the events that had gone on today.
