What to look for in the series finale: Many fans now point to George R.R. Martin's series title, A Song of Ice and Fire , as proof that Jon Snow, the physical manifestation of the wintery Stark clan and the dragon-rearing Targaryen family, is the prince that was promised.
Emily Dreyfuss, Senior Writer: Having read all the books and watched every episode of this show, I have to admit that I still can't remember what's happening at this point of HBO's Game of Thrones . Dreyfuss: Jon Snow (Kit Harington) looks like he just realized Daenerys is his sister … five minutes after they slept together.
