Honoka basically goes purple because somehow this isn't the outcome she expected. Genius.

Rather than immediately get into bloodletting, Honoka tries bargaining and says that she would LOVE to give this warlock some of her blood, but right now she's on an important mission and she'd probably get all kinds of sick and woozy if she tried getting into bloodletting before she got on that business.

BUT! She promises to come back once she's done with that blood. Seriously. For real. She's being as capital-C Charismatic about it as she can manage.
