When we pick back up with Meghan she is cold and confused, standing in a grocery store hoping for someone to meet her. Although the connection is eventually made, Meghan’s first attempt to deal with an unwanted pregnancy is a fail. Remember, this is 1966, before Roe v. Wade, and its eventual overturn. Besides which she is only fourteen.
Triese is her saving grace through all of this, but even a guardian angel could not fix what was wrong with Meghan. So she decides it is time to go public, as it were; at least time to confront Danny Boy with the unhappy fact of her pregnancy.
