In Life of the Party, still reeling from his loss to Urkel, he plotted revenge against him. At Maxine's rooftop party, Steve impresses the crowd by teaching them to do "The Urkel Dance". Humiliated, Willie spikes his cup of punch with the smuggled small bottles of alcohol hidden in Waldo's trench coat. A drunken Urkel hangs by the clothesline and fortunately Rachel was able to save him by tightrope walking and pulling him to safety. Laura confronts Willie and Waldo about their actions. She tells them off Steve could've been killed if it wasn't for her aunt and that smuggling alcohol and then spiking someone else's drink isn't cool. Willie has been sent to Juvenile Hall and hasn't been seen since.
- As Waldo is his only friend and sidekick, Willie has been very frustrated with him. The first time was in Requiem for an Urkel, when he unnecessarily asked Willie why they trash Urkel's locker on a Tuesday. This was shown in Life of the Party twice when he told Laura and the cops about sneaking in an illegal bar in his jacket.
- Willie seems to like Laura, but started to hate and antagonize her when he learned that she wanted to go with Greg Hudson. Infuriated, he scared Greg and all of Laura's other prospect male dates with the things he will do to them if they are caught going to the dance with her.
- Although Willie like to bully Steve on a daily basis, he began to despise the nerd for defending Laura's stance in choosing to go to the dance with Greg, He didn't think someone brave enough ot even dared to stand up to him in the manner that Steve did, causing a fight between them.
- Although Larenz Tate had a remarkable performance on Family Matters as Willie, he wound up appearing in only 2 episodes. Both Tate and Shawn Harrison (Waldo) were offered recurring roles on the series, but only Harrison accepted, while Tate moved on to other projects such as the film "Menace II Society: and the short-lived series "South Central." After Tate left the show, Waldo's character was rewritten as Eddie's best friend.
