Question: If Tavington and his men had succeeded in finding Martin's family at the plantation, would they have just killed them or taken them hostage?
Question: At the end, when Martin and his family go back to their old home, why isn't Abigail with them? She loves them and they are like family to her.
Question: Why does Susan refuse to speak during most of the movie?
Answer: She is angry, mostly from missing her mum, but also at her dad for being away so long and often.
Answer: Abigale, along with the rest of Benjamin's slaves, was taken away by the British earlier in the film. We don't know what happens to her after that, but more than likely, she was sold or given to another slaveholder. Slavery continued after the war, so she would have continued with her new household. We can speculate that maybe, after the end of the film, Benjamin may have tried to track her down and possibly buy her back, but either way, she likely remains a slave.
