Long-lost bunny has come home...but seems sad - what can I do?

My little mini-lop Clover escaped about ten months ago when two huge dogs attacked her hutch and ripped part of the roof off. Now, ten months later, she has come back - I don't know where she has been, as I searched for her for weeks everywhere I could think of, and had food out for months in case she came home. But back in her hutch she seems sad - maybe bad memories? She is cuddled lots every day, let roam on a bunny leash and given many treats and much affection and grooming. I now have two seal point mini-lops who are sisters, who I will introduce to Clover once she has been given the all-clear health-wise, but is there anything I can do to make her feel safe and at home again?
