I think they probably did but I hated that they wrote that into the show. When I realised what direction they were going I really didn't understand the logic there. M&S have had a natural chemistry and relationship and it seemed the romantic part of their relationship was just a natural progression. With D&R it just felt like it was quickly thrown into the 表示する as it was starting to ラップ up. Didn't see it coming and still don't get it!
