Finally some hard evidence on what happened. Except that it doesn't really tell us the who or the why. And what's Partridge up to, anyhow?
I like Redmane and the fact that he chose this moment to make another appearance tells me there is more to this so-called animal than Trex may think. Could be a real sentient life form and I wouldn't be surprised if he's somehow connected with what's going on here.
