I sincerely hope you are right, I really do hope the family's time with Ralph has come to an end, there are two things that make me unsure though:I sincerely hope she's able to get away from Ralph. Not to powerlevel but I used to do a lot of stupid things when I was in my late teens and early 20s because I was undiagnosed/misdiagnosed. I certainly don't have any kids thankfully, but I made a lot of terrible relationship choices and got suckered into a lot by wanting to believe the best and ignore the facts in front of me. I ended up homeless for a while and the idea of being homeless (and going back to the fight or flight only mode) again definitely keeps me from "relapsing". Hopefully her time at Ralph's crack shack is something she can do the same with.
She may not be the brightest one out there, I'm sure as fuck not, but the right medication can be the catalyst one needs to get their shit in order. It sounds like she has a decent support system and having a job, even if it's a benevolent act by her dad, can help someone keep the future in mind. I'm rambling at this point but I guess my point is: BITCH STAY AWAY FROM RALPH!
It seemed like she still wanted to go back to Ralph even after being medicated and that the only thing that changed her mind was Ralph bragging about having sex with May.
When she mentioned medication, she mentioned something about it being pregnancy anti depressants (can't remember the exact quote), and it seems to me that someone like Faith would need something more than that.
Either way, I really do hope I'm wrong about all this and that Ralph is just lying like he usually does to keep up the appearance of things going well. I guess we'll find out soon enough once Xander is born.
