Arthur had no idea how to comfort his wife. He killed numerous people. The bloody history he left was awful. However, he never killed his friend.
As for his wife, Catherine was her one and only childhood friend who accepted her for who she was. Catherine was a part of her life and heart that even he could never be part of.
It wasn't that he was jealous of Catherine and his wife's relationship. He was glad that there was someone his wife could rely on other than him especially when he wasn't by her side all the time.
In the end, she killed her best friend with her own two hands, just to save the man Catherine loved.
As much as it hurt Catherine, it burdened Veronica for rest of her life.
"Arthur, do you think I'm a murderer of my own friend?"
Shocked, Arthur gazed at her. His arms tightened around her.
"No Ver, you didn't kill her. You kept your word and saved the man she loved."
