Charlton bowed his head as he walked back to his seat after he played the cello. He was afraid that his eyes would betray what his heart desires.
When he saw Serena about to fall the stairs earlier, God only knows how terrified he was that he was afraid his heart might lurch out of his ribcage. Thankfully, someone caught her. But when he saw Geoffrey with his arm wrapped around her waist, he wanted to do nothing more that to rip her away from him, so much so, that he felt his hands tremble. When Leonard left, he quickly excused himself from the conversation to follow.
As he approached them, he saw how Geoffrey's eyes lingered on Serena as she dipped into a curtsey. He was immediately assaulted by feelings which he knows he has no right to have. He could hear his ears ringing but can only clench his jaw to hide his frustration.
