In "An Early Arrival," what delivery does Terry get, and what does Tova learn about the new delivery and Marcellus?

Terry gets a delivery when Tova is at the aquarium on Wednesday. He tells her they have arranged to get another octopus since Marcellus is at the end of his life span. The new octopus is a female that got trapped in a crab pot and has been rescued. Terry tells Tova that Marcellus was rescued too. He was missing half an arm and his body was all chewed up.
