Lydia was getting ready to down another shot when he spoke that last sentence and she froze. Her first thought was simple, "But Arran doesn't have a-" and then it all hit her. Cariad. Her and Arran had broken up over a year ago hadn't they? Unless she was really out of the loop and they had gotten back together. Then again Roger or Arran would have told her that wouldn't they. "Oh," was all she could mutter while her brain tried to process this. "Is that why they broke up? Because you did that?" That would have meant they hadn't been friends for a long time and how did anyone not notice anything? Sure Arran had training and the season but were they all stupid for not saying anything.
Then more thoughts were coming to her brain and she really couldn't stop them from coming you, "Roger you never liked her, why in all the world would you sleep with her?" Lydia hadn't been super partial one way or another towards the other woman, mostly because her two friends were on totally opposite sides of the spectrum on this one topic and she wanted to keep the peace. Shaking her head she ran her hair over her face, "Please tell me you had a decent reason for doing this," she begged. Roger wasn't great with relationships, she knew that but this was even below him.
