Wrench's Literatures
Melt takes on a humanoid form for three reasons.
Melt tries to help Wrench "work".
Cheese Melt discovers that humans, including his beloved Wrench, are prone to something called "Sick" (awfully similar to literature he's consumed of egg-laying in repto-mammalian creatures, but c'est la vie)
Melt prepares to go to a faculty dinner with his husband Wrench, who is less than enthused to be around a bunch of untrustworthy academics.
