He was serving a meal and made pie for desert at request. His employer injected the pie with poison to kill the people eating. Roger was knocked out by a bottle of low-sodium soy sauce in the struggle to stop him. When he woke up, he found everyone was dead. He then took a lifeboat and left the ship.
Roger managed to get to the boat Rent-A-Dream where Marge and Homer were having their second honeymoon. Here, he baked them a pie to say thanks for saving him. Homer thought that it was poison and threw it out of the window where a shark ate it and died. They then saw Roger making scones and decided to try and kill him.
Marge seduced Roger while Homer turned sharp on the wheel, causing the boom of the ship to hit Roger and kill him. Homer then washed him into the sea with a hose where they thought he would rest forever.
Later, the Rent-A-Dream comes across the Albatross and Homer and Marge find out that Roger's story was true and thought that they killed an innocent person. Roger then comes into the room, covered in seaweed, telling them that it was true. Homer then shot a spear through him, killing him because he might tell that they attempted to kill him.
