[Smart move Haruhi. Homura wouldn't really tell you about it anyway. She goes to the crate and begins loading the gun with the illusionary ammo for the dome session with little fanfare. Once it's done and securely loaded she turns to Haruhi again.]

Thank you. I'll teach you here just how to properly hold the gun and aim it. It's important that if you get attacked you keep yourself calm and collected throughout.
