She went straight to the bathroom and locked the door to get some alone time. Gary was putting away their bags and separating their dirty clothes for the washing machine. When he tried opening the bathroom door, he was surprised to find it locked. She never locked the door of the en suite bathroom. He knew something was wrong. He used the other bathroom to bathe and he was lying on the bed waiting for her to talk it out. She took too long and he fell asleep. He was really tired.
