They made it halfway down the third tunnel back before Henry threw both of them against the wall, a hand pressed roughly over their mouths.

Richard clutched at his wife's arm, painfully tight, and Henry squeezed them warningly.

One noise will kill us. He tried to tell them, and he couldn't tell they understood, or if they were just too frightened to make a sound. Silently, Henry slipped away, using every instinct his HAP side could lend him without a full transformation.

Especially the night vision. God, he loved the night vision...

There.

The wendigo, as tall and twisted and inhuman as he remembered the last one being, lurked in the darkness around the corner... mere feet away from the crevasse he'd shoved Richard and Emily into. Henry bit his lip and eased back a step. He needed to think.

There was no way past the abnormal, and as far as he knew, no other way out of the tunnel. He had two options. One, try and hide with the others until the wendigo was past, and hope they didn't get caught. Two, let his HAP side out, fight, and hope he survived while the others escaped. He couldn't even tell Emily or Richard what he decided without risking the wendigo hearing them and attacking.

Will's never going to forgive me for this, he realised. Will, I'm sorry. I love you; I just wish I could kiss you one more time.

He slid back to the gap he'd pushed the McCords into, and pressed them back even further. He slipped in front of them defensively, and waited. He could feel them trembling at his back.

The sick-sweet smell of decomposing flesh and old blood gagged them all as the hulking form slumped past. Seven feet tall, skin grey and rotten-looking, jagged branched horns scraping the ceiling of the cavern. Emily buried her face in Henry's shoulder, too frightened to look, and Henry felt Richard stiffen, transfixed with terror and disgust as he finally knew that Henry was telling the truth.

The creature grumbled softly to itself, wordless sounds that made Henry's heart clench at the sorrow and pain in its voice. This abnormal was so similar to how he had been before meeting Magnus, so alone... he banished the thought. That was how the wendigo hunted – it played on the human instinct to help others.

The creature was almost out of sight in the darkness by the time it had shuffled past their hiding place, but then it lashed around, fast as lightening, and gripped Henry's throat in a hand so gnarled it looked like thorny branches.

"Run." Henry choked on the wendigo's stench. Richard and Emily tried to wriggle past towards the exit, but the wendigo threw out an arm, trapping them. "Get out!"

He hurled his bodyweight forwards, and pushed, transforming fully. The werewolf snarled viciously at the other abnormal, and the wendigo staggered back, thrown off balance by the sudden resistance. Emily's short scream reverberated in the narrow tunnel, the echoes blending with Henry's snarl of challenge and the wendigo's harsh cries.

Henry lost track of what happened, lost track of Richard and Emily, totally focused on his opponent. He saw the creature in perfect clarity, thanks to his wolf eyes. The stench of decay and blood was thick and cloying in his throat, and only served to incense the werewolf more. The only things his instincts really registered were the fight, and the feel of yielding flesh beneath his talons... and then the taste of fresh blood on his tongue.

The bright metallic flavour brought him back to his senses.

The wendigo was supine on the floor, black eyes wide and blank... throat torn out. The creature was alive; even having ripped away most of its airway, he doubted he'd done enough damage to kill it. He withdrew before he could do anything else, and turned to face the McCords.

They had been trapped in the tunnel with the abnormals, unable to work their way past the fight. Richard was almost on top of his wife, shoving her as far back as he could from the werewolf.

Richard lunged forwards, and levelled Henry's gun at his head. Henry froze, and tried to reassure them, but all that worked its way out of his throat was a helpless whine. Mentally he cursed himself; he was still transformed, of course he couldn't speak!

He took a tentative step forward, and whined again as Richard only moved to steady the gun with both hands.

"Wait!" Henry huffed a sigh of relief as Richard turned towards the voice as light flooded the tunnel. If Richard wasn't paying attention, his aim would be off, and looking at the light after being in near pitch darkness would ruin his night vision. "Don't shoot!"

"I thought you were in Marrakech." Richard managed. Will skidded to halt, panting.

"I was. Just got back." He rested a hand on his friend's arm gently. "Put the gun down, Rich. He won't hurt you; he saved your lives."

"What-"

"It's just Henry." Will moved to pull the werewolf into a hug, and Henry transformed back in his arms. Will immediately wrapped his coat around his lover – Henry had transformed so quickly he hadn't spared a thought for his clothes. "I got your message."

Henry melted into the larger man, and kissed him softly.

"I'm just glad everyone's alright."

And then his world faded to black.
