One plot could be that they try to manipulate Harry through his close relationship with Ginny. Another could be that they use family connections and old wizarding laws to try and claim a part of the Potter fortune. This would lead to a rift not only between Harry and the Weasleys but also among the Weasley family members themselves as some might oppose such actions.
