Abortion
It's famously difficult (or impossible) to deal with the issue of abortions in films nowadays. If someone get's pregnant you can bet your lunch money they're going to keep the baby, regardless of how inappropriate it is. Or if an abortion has happened in the past it must have completely ruined your life. That seems to be what's going on with Gena's character. She had an abortion about 15 years ago and therefore she is now a waster, drug addict and completely dead inside?
