Aiden had NEVER seen his boss like this in all the years he had worked for him. He was honestly tempted to panic too at seeing such a stoic person sobbing like the world had ended. Well, for him it probably had. He knew better than any of Aaron's other friends how much his wife meant to him.
The whole reason he even bothered taking over his father's company…the whole reason Aiden ended up working for him in the first place…was to take revenge for people who hurt Keeley in the past.
He had always vaguely wondered what Aaron meant when he said only he and Keeley could remember what happened with those people hurting her. But today had kind of cinched it for him.
Before he got too incoherent, Aaron said 'I'm going to lose her again.' Which implied he had lost her before. Then he went completely catatonic after the horrible sobbing stopped. As if he had already given up on the thought of his wife being alive even though she was clearly still fighting.
