Eiro was floating within the sea of shadows as he glanced at the crow. He could see their expression, and the way that they glanced down the hallway. If Eiro just kept on playing around like this without actively engaging the crow, they would just run down the hallway and catch up to the others, killing them while Eiro wasn't there. That's what he could gauge from that deep gaze.
With a click of his tongue, Eiro swam around the cave's shadows, dropping from a stalagtite's shadow down onto the crow from above, "What an annoying little brat you are," the Demon pointed out, "Even my eight year olds don't have attention spans as short as you."
