An old promise reminds you of him. Xiao. He told you to call out his name if you ever needed him, and he'd come. Anywhere. Anytime. Although you aren't currently in danger, you still call him nevertheless. His name experimentally rolls off your tongue. Within seconds, he materializes out of thin air in front of you. He really did come...

"You... came?"

"You called."

His response was short and curt, but there was an undeniable warm undertone to it. You can't help but smile.
