Whilst family matters in the Snart household are clearly in the toilet, things arent all roses and rainbows for the Wests either. Following on from Joe trying to pay off his recently-turned up ex-Mrs, we find out just why the usually above board Detective West resorted to throwing a large wad of cash at a problem. In a bombshell moment, its revealed that Iris mother used to be a drug addict. Concerned for his daughters welfare, Joe felt that he had no choice but to cover up Francines issues over all of these years. Again, this was a move in which The Flash confronted some pretty serious issues for a show so often depicted as being merely about some really fast guy in a red suit saving the day.
