See, this is the problem with shows that take too long between seasons and have too many characters. You will always forget key elements of the story like this one because there's just too much information and you can't know what is or isn't relevant.
I've been rewatching the whole series, noticing a lot of stuff this time around. R+L=J is ridiculously obvious.
If it's too complex you can always go back to any number of simple shows.
Raven is Brynden Rivers. One of four great bastards.
