I'd like to pick up the bottle of drain cleaner, hold it near to my face, then fall on my back and throw out my arm. Does the bottle end up anywhere close to where it is?

Not really, no. It's too close to where you fall.

Trip, did you go down with Terezi to the horror set at the same time?

Yeah, she came down with me. I ran away when I saw the body though, dunno where she went after that

To clarify the earlier autopsy at someone's request: Hannibal has no other wounds.
