I used the rat poison in Timmy's food, but it just takes me to the Freeloader ending... somehow. Did I do something wrong?

P.S: I got the true, road trip, and previously mentioned freeloader ending. How do I get the rest?

Update: I got the Jail Bate (sic) ending! Turns out that I don't NEED to eat with Timmy, just tell him to eat dinner when there's only one plate on the table.
