Aqua squeeze Myca's hand tightly and wraps his arm around the arm of his friend. Even with Myca's reassurance, he clearly doesn't feel all that great about this crossing the street thing. He trusts Myca to not lead him astray (it helps that anything that happens to Aqua upon crossing would happen to Myca too, given the way the selkie is wrapping himself around him. An unintentional way of assuring his own safety) but he's still nervous about it. "The signal makes them stop? Are you sure?"
