Mark is home and tells Juno that he is leaving Vanessa. Vanessa comes home and Mark tells her everything. Juno becomes upset because she doesn’t what her unborn baby to be brought up in an unstable household. Juno leaves and after time alone, she comes back to Mark and Vanessa’s house and leaves a note on the doorstep. Juno then gets back together with Paulie.
