Colonel Regan is a Patriot. Isabel visited him to explain to him that Mr. Lockton and his comrads had a plan to kill General Washington. He understood Isabel and was nice to her. He promised her that he will try hard to set her and Ruth free, but he didn’t give her the freedom that he had promised her. At this point in the story, you can see that he is not as nice as it first seems. He just wants freedom for the Patriot’s, not for the slaves.
