Trixie wanted to help Noah to reverse the curse on Lyka. She told him to return to the place where it all happened from the time of Argos. She told him to meet Remus at the mountains, but warned him of the obstacles. While Trixie is saying this, her back is being whipped invisibly, maybe she is being punished for what she is doing.
Alec accompanied Noah to the mountains as he has an idea on where Remus might be (being a descendant of Remus). But on their way, black wolves surrounded them. As they run, they went on to a dead end (a cliff).
