Gokudera's first reaction was to get himself physically between Ryuutaro and his father, his next step was to get Ryuutaro somewhere safe... because he knew this wasn't going to end well for someone. If that wasn't made more apparent by the older man reaching for something in his suit jacket. Hayato pulled out his own weapons and looked over his shoulder at Ryuutaro.

"Ryuutaro, go outside with your dad. I'll take care of this."
