Yeah, I do like Guy, and I will feel bad for him if Caroline and Mac do get back together. But at the same time, I don't think Caroline's feelings for Guy are as strong as her feelings for Mac, so it's not really fair to him for her to be with him. At least, in my opinion. For all I know, she has been secretly in love with Guy for all this time and they'll make a perfect couple. But yeah, I do want to see Guy happy in the end.
