Eva originally had no intention of eavesdropping. She walked over there unintentionally and planned to leave upon hearing noises but accidentally overheard Hayden's name. She couldn't help but listen.
The more she listened, the more confused she got. Why was Clara talking to Abigail about Hayden and asking Abigail to forgive her?
Finally, Clara asked Abigail if she disliked him. Was "him" referring to Hayden?
What right did Abigail have to dislike her brother?
Eva was still dumbfounded when she returned to her room. Her mind was full of wild guesses, making her frown more and more. Unable to figure it out, she decided to stop thinking about it altogether. The pain in her chest became more prominent. She tried to ignore it and looked down at the materials her son had thrown to her last time.
