The ball that is now the boy's head rolls away, and Thomas is seriously freaked out.
The boys all gather around, and Winston deems the boy to be Frankie. Daw, poor Frankie.
Newt then finds the metal ball; it's covered in blood.
Again, everyone starts freaking out about going back, but Minho tells them to just run forward as fast as they can while ducking.
Along the way, a death ball gets another kid.
The boys stop when Minho hits his shin on a staircase. Well, we guess there's nowhere else but up from here on out.
The kids all climb the stairs, and Minho finds a door-thingy. He opens it, and everyone is blinded by a huge light. Heat rushes in, and Minho's forced to close the door because everyone's eyes are now toasted.
The kids wait for a little bit with the door opened a crack so that their eyes can adjust to the light; then Minho opens it again. The light is excruciating, as well as the heat.
The boys feel like there's no way they can venture into whatever the light is, when suddenly Winston yells.
A giant glob of liquid silver forms on the ceiling, plops off of it, and then floats toward the boys horizontally.
The glob forms a sphere of silver and flies directly into Winston's face, causing him to tumble down the stairs, screaming.
