Tony sure gave Carolyn the cold shoulder after her sudden change in mood upon hearing the dogs howling, telling her he won't be free for lunch that next day. Too cool!
I think Julia should have taken her own advice and left Collinwood, but I think some small part of her wants to believe there's a bit of goodness in Barnabas, despite the appalling way he treated her!
I love Barnabas, but I can't really defend his behavior towards Julia, it was downright cruel, leading her on like that. Even Carolyn, who is under his control, thought it was terrible.
