I know there are only a few episodes left, but why didn't Renard contact his mom and let her know he had located Diana? She might have tried to rescue Diana and Renard both from BC. I know Renard said it was hard to reach her, but they were able to call her when he was shot she was there ASAP. I know this would have changed the plot, but still, it might have provided some interesting fight scenes between her/Conrad/Eve/Adeline .
