Jesper and William made their way down the staircase (assuming that Jesper takes the lead.) The growling sounds grow slightly louder as Eddie continued to fiddle with the buttons on the soda machine.

There are half a dozen scientists in the lab and they are completely focused on Emily's injury. They are actively running around, applying pressure to the wound, and fetching medicine. Emily is unconscious and laying on a wooden table on the opposite end of the lab. 

In the center of the lab are several boxes of sorts, with blankets thrown over them. Although their layout is seemingly random, the boxes aren't scattered around the floor. They seem to be deliberately sorted. 

Oh, another interesting things about these boxes- Whatever was under these blankets was definitely responsible for this growling noise.
