Wash gets out his comm to film what's going on.

"We didn't find anyone but we did find this."

He points the camera at the crushed monster embryos fizzing in bleach.

"We crushed them and then poured some bleach just to be safe."

Then the cloud erupts and he backs away.

"Uh, thaaat's not good. Guts, maybe you and I should... should clear..."

Whump.

And then he's down, comm dropping out of his hand. It's still recording.
