Roarke knew he felt attracted to Nessa, if the constant sharp grey eyes which hunted him daily even into the realm of oblivion isn't enough despite the fact that he had changed the location of the painting which held a similar colour of her eyes. The tensed atmosphere and how his body came alive whenever she was nearby was enough.
He didn't think there was a day which went by without something or someone reminding him of her. Be it at work where she went around being in the middle of a circle of people or at home where Ari won't stop mentioning her name or something she saw in her office.
It was quite amusing how his daughter didn't believe him when he told her someone who draws is called an artist, only for her to spend some hours with Nessa and she believed her, even though they had said the same thing.
