After Squidward reads SpongeBob's diary, Quincy comes to repossess Squidward's house.
Relationship with SpongeBob
He seems to dislike SpongeBob. In The Card, he seems to have dealt with SpongeBob before this episode and disliked him from that. In Model Sponge, Quincy does not like that SpongeBob makes a "Krabby Patty" out of money. He then fires SpongeBob.
However, in "Little Yellow Book", he somewhat defends SpongeBob after Squidward reads his diary.
"SpongeBob, I don't think they give the money directly to Mermaid Man and Barnacle Boy."
