It really was so unnecessary. What was the purpose of it? To give Kate something else to do? She had both her siblings in the hospital, could have helped out her cousin with the newly returned son. To make Rana jealous? That barely happened, and it could have been just as effective by having Kate open up to her with Rana mistakenly thinking they were more. To show the contrast between Kate/Sophie and Kana? They barely showed Kophie and had to write Kate like some different person the whole time. They’ve treated her so harshly, with the way the break up’s going to happen, for no real reason.
