At the party

John went out and hit both Cardi and Karen with the Memo-Ray. He also made them both sisters, just for fun. He implanted memories in everyone (including Lizbeth and Tracey) that would make them attracted to the opposite personalities. What this accidentally did was make all of the girls have massive crushes on their siblings, but John decided to leave it like that for fun.

At the party, Tracey was staring longingly and voyeuristically at Lizbeth, and because of that did not notice when she accidentally walked into Willa, who was filming a TikTok. The girls fell on top of one another and locked eyes, falling madly in love instantly.
