I'm proud of her. I know I've run Sam ragged in the past. I know I can be a little paranoid and a little mother hen around her. I can't really help it. She thrives in the light of a club or among all the boys in the bar. But I forget all the adventures we had backpacking and exploring in University, sometimes. She's capable of keeping up with me, I just have trouble keeping up with her. She used to drag me out to clubs and bars for hours at a time.

We've only been out to a club three times since Yamatai. Attempts to be normal for a few hours, to let sound and music wash over us. The first time, I broke some poor bloke's nose. He danced up behind me, and like a rubber band snapping I was back on Yamatai. The second time went a little better, until some perverted older man grabbed onto Sam. Sam paid him off after I broke his wrist, but it wouldn't have taken much for me to break his neck instead. The third time was just before this trip. In part, it is the reason we've gone as quickly as we had. I needed to get away from civilization. I need to be part of the wilds and the ruins again.

I'm not normal any more. I'm a wild thing. Not that I was ever one for the club scene, but I have trouble when large numbers of people are round. I always preferred being solitary, but never minded people. Now, I jump when a car backfires. I hear my name and blink my eyes as I return to the here and now. "Sorry, Sam. I was just thinking about something."

"Like what?"

"Like how I'd probably fall apart without you."

Sam has this look she gets when she's trying to not gush with emotion. She knows I'm not fond of public displays in general, and I think she's realizing that she can't pounce me for kisses when we're out and about. Most of the time. At least I hope she does. I kiss her anyway - who's going to watch us here? It wasn't like we didn't hold hands at the drop of a hat. I don't want her to feel like I don't want her, and I feel suddenly a little raw. I really would fall apart without her. She's the only family I have left.

I break the kiss and don't risk looking at her, before moving farther down the tunnel. I can hear water, and I flash my torch around to make sure I'm not going to topple suddenly. I had enough water-slides to last me a lifetime on that island. I'm pretty sure half my scars are from those.

"Lara?" Her mouth is right next to my ear and I'm startled at how silently she'd moved. I move my hand away from the axe at my hip, and take Sam's wrist.

"Careful." I'm a lot better than I used to be. But it's still a nightmare of mine that I might kill her. That wild thing that woke within me on Yamatai. Sometimes she wants blood. I have no doubt that under the right circumstances, I could do it all over again.

"Sorry." Her sheepish smile relaxes me, and I let her go, turning back towards the tunnel as we emerge into a chamber.

I move my torch around, and use the flash on my camera to help illuminate where we are. To my left, Sam is doing the same thing, and together we complete a full sweep in just a few minutes. We work so well together that I question why I thought I could leave ever leave her behind.

I approach some writing and try to decipher it. Something about the worthy. It's surrounded by more faces, their expressions distorted in horror. The hackles on the back of my neck raise and I have the distinct impression something is watching. The ground rumbles, and the world drops out from under me.
