Lottie is usually seen as peppy and bubbly on the outside, although at times she can be very twisted. In the past she seemed to have a far more innocent character, and had better control over her emotions.
To be honest, I feel so very connected to Lottie's character. I have also tendencies to be so bubbly and full of energy, yet there's still something dark behind my personality. xD Twisted in my own little ways *evil laugh* i mean haha
