Tanya's. The episode was really well written. I loved how they finally acknowledged how toxic Max and Tanya were together and that no matter how much they want to be together, they really shouldn't be.
I know she wasn't everyone's cup of tea but I'll miss Jean. She was one of the very few characters I actually cared about. With that said, while her final scene was touching, I am sick to death of these rushed exits where characters decide they're leaving Walford one minute and are on their way the next. Still it was nice that Jean got a happy ending because she deserved it. Just a shame she had to leave at all really.
