If we're looking for a valonqar, look no further than Jon Snow, the younger half-sibling of Aegon and Rhaenys Targaryen. Reddit user dremling believes that since the version of the prophecy, as outlined in the books, is in High Valyrian — and Targaryens have Valyrian blood — Jon Snow stands out the prime candidate to put an end to Queen Cersei. Not a bad theory, especially when you consider that his love for Daenerys might push him to take such drastic action.
