Whilst Jessie seemed to be relaxing in the Caboose in fact she was focused on the senses of Karl, her Raven familiar who was sitting watching the engine in case anything went wrong. Not that could mention how she was doing it, she reckoned good god-fearing folk might not be too pleased to find a witch on their train, especially with what she'd heard about the Wichita Witches.

"By the pricking of my thumbs, Something wicked this way comes!" she mumbled dramatically loud enough for those nearby to hear.
A little drama didn't go a miss either, helping to sell the image and prevent trouble further down the line!
