The instant the suit lights go on, the away team can see parts of floating Klingon blood. It seems to be coming from behind the door. A partial glimpse of part of a hand and fingers can spotted behind the door as well.
Floating in the corridor and slightly mostly dead is a tribble. It apparently was used as target practice. Which doesn't look too out of place in the room. Several black patches that look like either phaser or disrupter fire are along the walls.
A Klingon warrior looks to be partially fused in the wall near the corridor entrance closer to the ceiling, clearly a sign of failed transportation. His mouth lies open in silent scream.
The lights allow for a more clearer picture of the room, since not all parts were fully illuminated by the starlight.
