Lazerus, having been looking down the entire time, has seen where Xilla landed. He says, between a couple of coughs that have a really inhuman sound to them, "Something's rotten here.", then shouts down "I'm coming in!". Amazingly, the sound of his voice changes completely when the volume goes up; it comes closer to a hissing screech.
Giving Xilla 2 seconds to get out of the way, Lazerus jumps down, hoping to hit the webbing she landed in.
