Time to make move

On their way back to Skellington, Eduard Moriarty and Marceline rode in one carriage, while Eve and Vincent rode in another. Eve sat with her arms crossed, and Vincent watched her from the corner of his eyes. 

"Did my response shock you?" Vincent asked her, the corner of his eyes crinkling in amusement.

Eve turned away from the window and stared right into his red eyes. She stated, "I thought nothing could shock me more than you burning an entire town. But you exceed my imagination."

"I like to always try," Vincent smiled, showing off his fangs to her. 

"What is a blood marker? The registry, what happens if you break it?" Eve asked him, as she had never heard about it before.
