He first stays with Raj, but after Sheldon criticizes Aishwarya Rai, comparing her unfavorably to Madhuri Dixit, Raj leaves him at Howard's house. Sheldon talks instead of sleeping, so Howard gives him Valium, which fails to work, and finally takes him back to the apartment. The drugged Sheldon tells Leonard the secret. The next morning, Leonard suggests Penny should join Pasadena City College, but after she asks, says he does not mind dating someone who is not smart, at which she slams her door in his face.

After the guys return from a Renaissance fair and see Penny with her new boyfriend Eric, Leonard is approached in the Caltech canteen by Leslie Winkle, who proposes renewing their one-time "relationship". As she has grown out of one-night stands she suggests they take it slowly, first determining their compatibility on all levels before proceeding to full sex (if at all); Leonard can assume the "male role". During their dates, Leslie asks how many children they should have and evaluates Leonard's genetic defects. Penny dumps Eric after unsuccessfully using him to make Leonard jealous (including a competitive make-out session between Penny and Eric and Leonard and Leslie, Leslie helping Leonard make his point). Sheldon tells Penny he is uncomfortable with Leonard dating his arch enemy Leslie, but on Penny's advice he accepts the relationship. Almost immediately, however, Sheldon deliberately provokes an argument with Leslie over the validity of loop quantum gravity, which Leslie supports, and string theory, which Sheldon favors. Leslie expects Leonard to back her beliefs, but when he supports Sheldon, Leslie dumps Leonard, to Sheldon's relief. Sheldon then comforts Leonard with the fact that it's only nine months until Comic-Con.
