o Tegan just told Brax that but then Casey overhears her terring Cheryl that Darcy isn't his but to keep quiet. Casey tells Brax and he confronts Tegan who then admits that Heath is actually Darcy's dad.
Whether or not THAT is true, I don't know. But I'm not going to lie, I really hope it is a lie. I so prefer Heath fancy-free to parental.
P.S. I read the above comments and how the hell are you guys finding all this stuff out, about Tegan dying, and all that?!
