I've had Dora in my town since the beggining, and it's the second time that she asked to leave and I actually said yes.. I still have time to revert that, but I'm not really sure about that. Seeing other normal villagers that honestly look much more interesting than her, I'm quite tempted to let her go. But again, she was and still is my favorite up until now... So I'll just let you guys decide. Should I keep Dora or not?
