There are time in every life when the past comes back to haunt...
For Gabby, meeting Karly was the event that caused so much of his pain, so many bad memories to resurface. Before Karly, his life was simple, plain even, but the emotion she inspried in him, the way she cracked his shell opened him up to an entirely new world filled with so much complex pain and emotion.
Before... he could close himself off to those things. He could make himself not feel. Now, after her, his book is open and while it has permitted him to see a whole new side of himself it has also given free reign to the demons that haunt his tortured past. It has made him turn back and begin to face the horrendous traumas he has faced.
It has made him question whether or not he is strong enough to face those traumas...
