He's the Captain (TMR- Gally Fanfiction)

"You can call me Captain Gally. Don't be fooled by those shanks. I'm the real leader around here." He whispered darkly in my ear. His hot breath tickled the skin on my neck, instantly causing goosebumps to erupt throughout her body. Her wrists that were pinned against the wall on either side of my head by his grip loosened, allowing blood to flow freely again. Letting go completely, he gave her one last look over before turning and walking away briskly. He really is the captain.

She was their only flaw in their so called "flawless experiment." Subject 000 The Backup, also known as, Emma, was sent up by WICKED by mistake. She was just an understudy, supposed to be sent up as the trigger if Teresa had not been able to... say, "make it." It hadn't mattered though, Emma was still sent up to the Glade regardless of Teresa's state. But, Emma is special. Her memory was only partially wiped, bits and pieces of WICKED still lodged in a deep, dark corner of her mind.
Upon her arrival, the Gladers were very confused. Why would another girl be sent up after Teresa? After learning that the new girl holds crucial information, they take her in and grow to care for her. Gally in particular, holds a strong interest for Emma. Feeling the need to protect and guide her, he takes her under his wing.
