Why would Jimmy's ex lie about a pregnancy to bait him into staying with her? It's not like he wouldn't have found out that she wasn't telling the truth eventually. She likely would've faked a miscarriage once he confronted her about it, or was just biding her time with him until he left for real. The conversation the two later have at Jimmy's workplace paints her as exactly the kind of person to pull something of the sort.
Why would Rabbit living in a trailer with his mother be used as ammo against him? Nobody else in the movie is supposedly any more well-off than he is. This could make more sense once it's revealed that Papa Doc (or rather, Clarence) doesn't actually know what it's like to be poor and probably didn't realize that he wasn't within his rights to make fun of Rabbit for his home situation as everyone else in his gang thought he was just like the rest of them prior to his exposure.
Fridge Horror
I can think of a more in-depth reason as to why Alex and Wink had sexual relations. One thing we learn quickly enough about Alex is that she has ambitions to leave for New York to pursue a modeling career, and Wink could have facilitated this by acting as something of a couch producer as an alternative to a professional work contract or something like that. It could explain why they chose to get it on inside the studio instead of anywhere else, as he would've propositioned her right at that moment to get her to obey. Not to mention that this is Truth in Television as things like this have happened before, and may be the only hope for her, a Detroit girl, to make it in the industry.
What could've happened to Lily if she hadn't left the scene of Tha Free World's assault on Jimmy? Or if they happened to notice her crying out for him. They don't seem like the sort to just back down once they saw a kid, considering they still decided to go through with jumping him despite knowing one was in his care. Some even have a theory that what happened at the abandoned house had something to do with the gang, making a possible interaction with Lily all the more alarming. And if Papa Doc had decided to end Jimmy's life then and there, she'd have to live with the trauma of helplessly watching her older brother, the only person who made an effort to look after her all her life, suddenly die.
It definitely puts Cheddar's "it could've been Lily, Rabbit!" comment in a darker light, that's for sure.
