Landlord (unaltered present)
In 1957, he offered to buy the building off of Duke Russo. In an attempt to save the sub shop from going out of business in the future, the present Russos travel from 2011 to 1957 to stop Duke from selling the lot to Hune. This drastically changes the man's life; when the Russos return to the present for the final time, they find that Lenny Hune's son is now their janitor, and Hune himself is merely the owner of a janitor service.
