Mexico
At first, Emma was hesitant to tell Pablo that her friends had planned a trip to Mexico for her. Not only in Mexico but in some resort where there was surely going to be a lot of single men there looking for women to flirt with. But she told Pablo and he told her that he loved her and trusted her.
Pablo had no reason to feel insecure about their relationship at that point. He loved Emma and knew that she felt the same about him. After all, they were getting married in a week so he better have trust in her. He helped her pack and drove her and some friends to the airport.
