Dylan starts noticing Brenda, as he and Brandon work on cars. Jim asks Dylan questions about his earring. He takes a shower and Brenda walks in on him. He invites her to the movies with him and Brandon. They run into an old gal of Dylan's. They go back to Dylan's and listen to music.
Brenda and Dylan go to the movies, just them. They go back to his place, and Dylan gets in an argument with his Dad. And almost starts drinking, before storming out. Dylan freaks out, Brenda freaks out. Dylan kisses Brenda.
At West Bev, the students are getting around to the "sex ed" portion of health class. Steve volunteers to pick up the guest speaker, when the teacher's car break downs, and attempts to pick her up.
Brandon talks to Dylan about not breaking her heart. And tells him his sister is a virgin (in her business too much?) Kelly gives Brenda a pre-date pep talk (and condoms), and Kelly and Donna help her get dressed up. Dylan doesn't show for her date, but we find out that he was helping his dad skip town. They make up and make out. Brenda talks to her dad about not sneaking around. The guest speaker has a revelation: she has AIDS. Brenda asks Dylan if she's had unprotected sex and they decide to slow things down.
A good episode, but it seems like they took the Brenda/Dylan relationship fast, from just dating, but that's how it happens I guess.
