"Hmmm." Caspar's brow furrows as he considers that. "I am pretty good at yelling... but I dunno if that'll help here. Sure, I can be loud, but that won't change what actually scares me."

Maybe if it were just the storm itself... then again, things meant for storms have helped before. His fingers rub idly together, mimicking a familiar motion with a charm that he doesn't actually have with him. "Could give it a shot, though."

Or maybe it still won't help. After all, the value of that grounding charm had never actually lain in any supposed magic properties to him... but, hey. He's not one to shoot down a potential fix before he's tried it.
