The Dink Network

After the Bloody River, I killed the Zombies and got the keys, but when I opened the cell doors it appears that Cthunik has already died.
Am I looking for Cthunik in the wrong place or was I too late getting there?
I would appreciate any help that I can get as I appear to have come to a dead end.

No he's in that place... but dead already... hmmm I wonder how that works, I can't remember if I scripted that or not... if I get a chance I'll take a look at the code.

Found him eventually, still barely alive. I guess I didn't search the cells properly the first time.
