A Plot. Jacinta is at Degrassi with a purpose. During the UN icebreaker, Jacinta gets close with Dave and introduces herself to Alli. Alli is upset and Dave tells Alli that Jacinta is nuts and that there’s nothing between them but Alli is still wary. Dave goes back to Jacinta and invites her on a drive to get away from the school. In Dave’s car, Dave reveals that he’s taking Jacinta back to the train station to get her away from him and Alli. Jacinta starts to cry, and when the car stops at a light she angrily grabs Dave’s phone, gets out the car and sends Alli a break-up text as Dave.
Dave parks and flags Jacinta down. He apologizes for last summer but Jacinta is still upset and won’t give Dave’s phone back. She walks into the street not paying attention and gets hit by a car. As Jacinta is being taken away in the ambulance, Dave is crushed and blames himself. He drives back to Degrassi, where an angry Alli (who received the break-up text) is waiting. Her anger fades away as Dave gets out the car and explains what happened. Dave is completely distraught and in tears from the guilt.

He was inspired by Marisol, and he and Marisol have fun singing along and Marisol is now drawn to Mo. During the Model UN proposal, Marisol and Mo present their concert idea. Jenna (with a nice little callback to her anger at Marisol’s flirting with KC in part one of the season) challenges the motion but Marisol stands her ground saying that music, along with love can be universal. Marisol tells Mo she was inspired by Mo and she says that she likes him. But Mo reveals that the feeling isn’t mutual. Marisol then storms out the gym.
