I looked everywhere for this topic but never found it so I thought i'd start it, sorry if it's already in here somewhere and i missed it.

Ok so, I would love to see a flashback of what happened to Sophia in season 3. I was so surprised when she came walking out of the barn as a walker in season2 ep.7 I believe, so I have so many questions about it all and want to know what happened.

I noticed she had a bite on her left shoulder so she didn't just die, she got bitten. How did she get bitten? When she was walking back to the highway in the first ep of season 2, when she first got lost, why did she veer off suddenly in the wrong direction?why was her doll in a stream at the bottem of a cliff? did she fall down the cliff just like Daryl and got hurt and thats when she got bitten? was that really her sleeping in the closet in the abandoned house? did she nearly make it?

I would love to know the answers to these questions but what do you guys think happened?Do you think there should be a flaskback about this or is it better for it all to remain a mystery?
