When hope starts having visions of a girl that look a lot like Klaus, she tells Freya she starts to get curious. She just bits and pieces of the girl so she goes into more depth in the vision. She than figures out that Klaus had another child before hope but it looks like Klaus had actually loved the girl mother but he would have mentioned something about it. She shakes it off then tells everyone because he wasn't hybrid then. They go to the island to find them.
