Marked

A/N Hey My Lovelies!!!! Here is the next chapter!!! Hope you are liking this story!!! Enjoy<3

After a long while, John managed to haul himself and the unconscious Siren back onto his Star Sailor. He made a bed for Sherlock out of a pile of ropes and blankets, his long frame taking up most of the deck.

He used his Med Scanner to check the Siren for any internal injuries, when he found none, he moved on to repairing the external ones he could find. Once he finished with Sherlock's wounds, he checked himself for any damage. He found only minor abrasions and bruises.

He pulled out his Star Guide, taking a seat on the end of the boat and hanging one of his feet off the edge, trying to figure out where he was. The last of the three suns had finished setting, and the brighter stars were making themselves known in the inky blackness.

John's guidebook was old, not like the new digital ones most of his comrades used. His had been passed down through his family tree, hand drawn maps and diagrams, showing just how much humans had discovered throughout the centuries. He gingerly flipped through the pages, unable to resist the urge to read the notes and stories his ancestors had written.

"That book is ancient." The deep, rough voice of the Siren pulled John from his thoughts. Sherlock had woken and managed to push himself onto his elbows. "I can feel the energies pouring from it's pages." John looked back down at the book in his hands, smirking softly at the pages.

"It's been in my family since humans first started exploring the stars. I got it when my father passed." Sherlock dragged himself along the deck, wincing in pain as his wounds pulled. "Don't, you'll hurt yourself-"

"I'm already hurt John, what more could I do to myself?" Sherlock snapped, pulling himself to sit next to John. "Can I see the book?" John hesitated, pulling the guide tight against his chest before handing it over to the Siren. Sherlock ran his fingers over the cover, gently opening the pages and smiling at the drawings he saw there. The Siren looked back up at John, his eyes glinting with mischief. "This book is amazing." John grinned proudly, enjoying the expression on Sherlock's face.

"I remember my father writing in it when I was a child, telling me stories when he was sober enough to do so." John sighed heavily, the few good memories he had of his childhood weighing on his heart. "I started writing in it when I was in the War, carrying on the tradition as best I could."

"You were invalided home." John sent the creature a curious glance, not missing the blush that rose over his cheeks.

"Yeah, how'd you know?"

"Your shoulder." John rubbed absently at the joint, feeling the poorly healed skin under his fingers. "That scar is less than a year old, and you carry yourself with the confidence of a soldier. Also, your Energy Bow is military issue, but not the latest one." John smirked, knowing he must look like a gaping fool. "What happened?" At that, John's heart throbbed painfully and he looked away, the smirk disappearing from his lips.

"An attack, my patrol was killed, I survived." He replied curtly, standing and grabbing the mainsail rope. He walked to the port side of the boat, tightening and securing the line to the hook sticking out of the floor. "That Hope, the one that attacked us, why did it want you?"

"I am unsure. I was unconscious before I could really see anything. How did you get me away from it?" John blushed, hiding the redness by fussing with a knot.

"Precision, an Energy Bow, and a hell of a lot of luck." Sherlock chuckled. "That Hope, I'm pretty sure it belonged to a Bounty Hunter called the Spider." Sherlock's eyes landed on John, sharp and dangerous.

"Are you certain?"

"For the most part. It had a massive red spider branded onto it's middle. I've only ever seen that mark on Spider's ships."

"You've fought The Spider before?"

"Not him personally, but my old patrol had to confiscate a few of his ships once. He brands everything with a red spider."

"Yes, it's his- how do say- seal. Anything he claims as his own, he brands with that mark."

"How do you know this?" Sherlock chuckled darkly, wincing as he rose above the deck of the boat, spinning around and humming a soft note. John's body tingled as the energy around the Siren shifted. John's eyes widened as the scales that covered his black tail quivered, filling the air with the sound of a quiet snicking as they slid against one another, revealing a horrific burn along the length of his tail.

The burn was in the shape of a spider, a massive scar running clean through the pattern.

Sherlock had been marked by The Spider.
