Although the suspicions of Damian and Olivia working together had always lingered at the back of his mind since the moment Lisa told him that she had seen them together, Noah never really took it seriously. However, after seeing Damian and Olivia discussing right in front of their room, the suspicions that he had once considered irrelevant had resurfaced.
He had decided to come back and stay with Olivia regardless of her words, but had stopped the moment he caught a glimpse of her discussing with someone. He didn't really take it seriously until he heard Damian's voice.
"Damian?" Noah had wondered. He couldn't hear what they were saying, and he had to restrain himself from walking forward to confront the two of them. But he knew that wouldn't help him in any way. If they were really up to something, then it was best that he didn't let them know that he had seen them together.
