Ordinarily Calvin would've argued that it was past midnight and therefore time for bed, but given his sister's recent talk of bruises, he was pretty sure that that would constitute a Bad Idea. He shot Ben a look at his comment about the Disney Princess sheets and would've made a kill motion if he wasn't sure that Charlie would've seen it. Last time he'd teased her about them she'd be a little... sensitive.
To detract from the impending bruising (or Indian burning, although Calvin had sincerely hoped that his sister had finally grown out of that phase), Calvin focused on Charlie's movie idea. "Only you could associate champagne and pirates," he teased, smiling at her. "And don't even think about breaking into mom and dad's liquor cabinet again. I'm certain they don't have any rum."
