Mitzu giggles softly and shoots Kyoya a mock glare. 'Be nice to the poor girl with the crush.' She mouthed for she could understand falling for one of the hosts having fallen for Kyoya herself. 
Mori looks at Kyoya then at Shima inclining his head in agreement to the situation. He understood that Kyoya was the real string puller of the Club despite Tamaki being the 'king' so to speak and getting all the hosts together as friends. He takes immediate note of her bandaged state, a dark glare entering his eyes for a split second before the cool facade came back on his face. He didn't like when others used violence on the weak. It really was a sour note for him. Mitzu being her mother's daughter caught the dark aura coming from the man and slightly smiles in delight. It wasn't as big a reaction when Kyoya decided to let his inner demons out because as stated, Kyoya was more special to her, but still, knowing others dark sides made her own grin with glee.
