She Was Scared
The problems started when Mikaela told her parents that she was afraid to sleep alone in her bedroom. She would wake up in the middle of the night and find that she was all alone. Dex knew how terrifying that was for a small child.
Dex and Lindsey were understanding when it came to her fears, they assumed she only feared the dark. But soon enough, Mikaela began to cry whenever she was alone, even if it was during the day.
