9. Kate keeps a lot of secrets from him.
Perhaps it is just about building tension in the show, but Kate said that she believes herself to be responsible for the death of Jack. She may not be ready to tell him, but why not? They are engaged and are expecting a baby together. What good can come from keeping a secret like that? Yes, I know part of the reason for the secret is to keep audiences engaged to find out what happens next, but her shut down with this information to Toby makes her a little less likable. What is Kate hiding? And Why is she still keeping them from the man she loves?
