Ollie/Dinah (and Danny?) (slightly later in the evening)
Ollie was getting himself a fresh scotch when he spotted Dinah nearby. He hadn't seen her in a while, because, well, things had gotten awkward between them after he'd fucked things up again. The truth was, he'd stayed away from her on purpose, because he figured it was probably better if it was the last time.
Ollie was determined to put the happiness of the people he cared about above his own. He loved Dinah, and he knew he made her happy, but he also hurt her far more than a person who loved someone should. So he could get to a place where he was happy for her that she was moving on from him. Even if he had to pretend for a while longer.
He approached her with a smile. "Fancy seeing you here," he said. He could tell she was surprised to see him. "You look beautiful, Di. As always."
