This is totally just me thinking out loud...
If they were in this apartment subletting a room, that is quite small for 4 people. Whatever happened, how was the little girl not hurt or caught up in the mix? Thank god she wasn't, just can't get that part off of my mind. If the little girl really did get out of the car and go looking for WE because she was scared, I would imagine she would have done this no matter where they were at. I can see if Lonzie took something that he thought was candy and accidentally OD'd his sister would just assume he was sleeping.
Nothing is adding up in my mind or making any sense. I have tons of questions/thoughts and some I can't even put into words. Thanks for just letting me put my thoughts (for now) out here!
