Andrea could not stand being in the same car with Bree anymore. She felt awkward, she had just turned down Bree's feelings like she was cold hearted. However Andrea herself did not understand what was going on, so she alighted from the car and went for a short walk.
Bree had parked the car at a good distance from Megan's house, but from their peripheral she could see exactly what was going on over at Megan's place, who came in, who went out and the sorts, so she pinned her gaze that way, trying to put everything that just happened behind them, especially Andrea walking out and away from her immediately she confessed her undying love.
