The issue wasn't that Eleven swung that way, but that of all people she could flirt with, she chose the coldest person in existence. Dia seemed unaware of the pirate's feelings, but she still scowled at her for approaching.
"Get away from my path," the princess almost spat the words. "Unless you want me to make an ice statue out of you," as she said so, Diana waved her hand, and frost danced following it.
"That would be terrible," Eleven took a step forward, and the gloves on her hand protected her from the frost as she held the princess's hand. "Allow me to escort you out, then."
Arthur and Dia were both stunned by her smooth and intimate actions. The pirate guided the princess outside before the latter could snap out of it and slapped her hand away.
"You insolent...!" Dia began, but Arthur hurried to step in lest she kills his next captain. It seems the pirate was surprised by the princess's attitude but amused nonetheless.
