[spoiler]who was the guy in the room?

[Yuhaney]

it can't be a dog in the hole. Bsides the sound of the monster that was attacking was much more fiercly then a simple dog.The thing that attacked him was much more powerfull then a dog. And the sound was bigger and much more louder and scarier then a dog.Something attacked him...but it was not a dog, spider, or a worm(maybe). It was something else.What more could that mine have hidden??You people are always thinnking that are dogs or spiders. Think about the new stuff that is coming!!

Hmm, it might have been Charlie, or a very slender breed of the hunter creature.

You mean the Roach from Tech Demo?
