Stacy's brother Brad, realizing what was happening (she tried to ditch him), was waiting as she emerged from the clinic. After some idle chatting about the abourtiin and the guy, Brad takes her to get a bite to eat and promises not to tell Mom or Dad. In some ways, it was the most powerful moment of the movie...she clearly was not happy and Brad didn't castigate her.
Ultimately Stacy goes "back" to "Rat" and never returns to Damone.
I remember now. You forgot about what happened when Stacey’s friend found out mike damone did not show up or help her pay for the abortion.
