The movie was cut around horribly (although I watched it on a free platform that had tons of commercials so maybe it was the free app and not the movie's editor). Also, I think the subtitles left a lot to be desired. 

Who is the very young child that was shown a few times while FL is studying at home? Is FL lead a single mom? Is the child her younger step-sibling? Neither were ever mentioned but I'm asking because the child was there.

It wasn't clear when Coach died nor when ML's mentor (the very big guy) died. Wait. Maybe I've gotten that twisted. It was mentioned that Coach was ill but maybe he didn't die?

Please help me out by explaining what the heck was going on in this movie. (I did get the overall gist but the details were severely lacking.)
