Demetrius is a scientist who studies the valley's local wildlife. He can often be found working in his laboratory or outdoors taking notes.

Relationships
Demetrius is married to Robin and lives with his daughter Maru and step-son Sebastian. Maru is his daughter with Robin, and Sebastian is Robin's son from an earlier relationship. It is assumed that Demetrius is Robin's second husband, because there are 2 books in the bookcase of their room titled "Maximizing Your Second Marriage" and "Practical Tips For First-Time Step-Dads." Demetrius is very protective of Maru, as shown in her two heart event.
You can give Demetrius up to two gifts per week (plus one on

When your total earnings reach data-sort-value="25000">25,000g Demetrius will come by your farm in the morning and tell you about some research he needs help with. He will then volunteer to improve The Cave to either attract Fruit Bats or to produce Mushrooms.
At any friendship level greater than zero friendship points, you may receive a gift in the mail from Demetrius. The chance of receiving a gift in the mail increases as your friendship with Demetrius increases.

Six Hearts
Enter Demetrius' house while he and Robin are inside.
Details
You see Demetrius and Robin arguing. She asked him to get fruit, so he got tomatoes. She exclaims that tomatoes aren't what he should have thought of because they're not "real" fruit. He defends himself by saying that tomatoes are indeed a fruit and his mistake was reasonable. He asks you to choose whether tomatoes are fruits or vegetables. Your response will affect only his friendship with you, Robin's will be unaffected.
