Bastian let out a snort, a half-grin coming to his face at the words. Friendly was exactly opposite what it actually was, and he knew that she was being sarcastic. "If by friendly, you mean bitchy and kind of annoying? Yes, it was!"
He flopped back down onto the bed, running a hand through his hair thoughtfully. "...I can be perky." His grin got a little bigger after he'd made that comment, and he shook his head to let her know that he was just kidding.
Mostly.
He let out another snort that turned into a cough of laughter when she joked about the sheets. Pulling up his blanket, he replied, "I could probably also one-up those pink sheets if I felt like it. How do you feel about Batman?"
