Ok, so this is my first fan fiction, ever. I mean like ever-ever! But, I do really like this book. Leviathan is just awesome. I've learned more about world history from this and Hetalia than I learn in school, I swear. I am thinking of doing some alternate rewrites for Behemoth after this. This is the ending I wrote as if she actually got to finish her sentence at the end of chapter forty:

He frowned. "What do you mean?"

Deryn took a deep breath. "I'm not really a [boy]."

A sound came from the door – the jangling of keys. It opened and Dr. Barlow strolled in, her eyes darkening as they fell on Deryn.

"Mr. Sharp. What are you doing here?"

Forty-one

Alek was completely, utterly, and embarrassingly confused. How did he not know his friend, truly his only friend, was a girl? He stood there, mouth open, just staring at Dylan explain to Dr. Barlow why he was here. No wait, she. No wait, maybe he misheard! Yes, that's it. How silly he had been to mistake what his male friend, Dylan, had said. Dr. Barlow is staring at me, He thought. Did she ask me a question? Oh no, Dylan is staring too. Why am I blushing?

"I'm sorry, did you ask me something?" Alek asked.

"Are you feeling alright?" Dylan asked.

"You do look a bit flushed." Dr. Barlow commented.

"No. What me? No, fine fine, I'm fine. Did you ask me a question earlier?" he stuttered back. He couldn't help but continue to stare at Dylan. What if he didn't hear wrong?

"I asked you what you think we should do in regard to Mr. Sharp's orders." Dr. Barlow said. She had lost her initial anger when walking through the door and now actually looked concerned for Alek. "He said he has been told to inform the captain about anything of suspicion."

"And I told you I won't." Dylan stared at Alek, his big blue eyes locking with his sad green ones. "Alek, I promised I wouldn't tell." He insisted.

Alek said nothing but continued to stare into his friend's eyes. They seemed to be telling him something. "We won't do anything." He decided Dylan isn't going to say anything and Dr. Barlow is too sneaky to just come out and say anything. He could be safe for a while.

"Aren't you concerned for your friend's safety?" She asked

"Aye, I am. Which is why I'm keeping dead silent, ma'am." Dylan interjected. Alek smiled to himself. Boy or girl, Dylan was a very loyal friend.

"Yes, Doctor, I am. But I can't make… um… him say anything." Dylan's cold gaze made Alek want to shrink. Could the hesitation be enough to tell the lady boffin his newest secret, witch the same gaze confirmed.

"Well then." She said with a sigh. "Mr. Sharp, go take Tazza for his walk." Dylan let out a sigh of relief, Dr. Barlow didn't know yet. She slid her friend an apologetic look.

"Aye, ma'am" and the newly discovered "she" left. Dr. Barlow turned to Alek with a sly grin.

"So, Alek." She took a breath to hold back a laugh at his scared face. "When did you find out about Ms. Sharp?"
