She could have been turned into a toy at some point leading her to meet the toy soldier, but she could still have the memories of her human life prior to that been erased making her forget Ricky who appears to be her father.
She didn't recognize Ricky cause he acted out of his character and fled to deal with his injuries. Ricky would have a nice age to him so be might be her dad. The solider might be her boyfriend or just childhood friend.
