Answer: Since blood was dumped on him too she must have realized that he wasn't a part of it, so yes, she cared for him. In the book when Carrie touches Sue, they link minds and Carrie sees that Sue felt bad about teasing her and was trying to do something nice to atone, and had nothing to do with Chris' nasty prank. So yes it's safe to say she grieved for Tommy and forgave Sue.
