Why did bran want jon to know about his real parents? So something that has been bothering me since episode 3 came out is: why did bran want jon to know who his real parents are? 
Bran is painted as an emotion less "being" that only serves his duties as the 3 eyed raven and jon knowing about his parents didnt help against the night king so why did bran want him to know?
It cant be because he feels bad for him not knowing his mother....

Might it still be important for the war of the iron throne? But jon never wanted the throne. So my only guess is that sansa/northerners will find out and will urge him to go against Dany but I just cant see him doing that.
Any ideas?
