Death Knights **Spoilers for season 6**

[OberynBlackfyre]

Sooo with the return of Benjen Stark, we also get a glimpse into HOW the White Walkers are actually made- however it seems that we can somewhat infer that as long as the White Walkers are not made by the Night King through the altar, they may remain sentient.  Unless the Others aren't beholden to the NK at all, and just choose to follow him with a fierce loyalty.  

That being said, I think Benjen is amazing in terms of him being dead, still wearing the Black, and wanting to help "fight for the living" for as long as he can.  

Since he has the secret to making these Death Knights, do you think Benjen will try to use that to his advantage in the war against the Others?

For instance- it'd be so awesome to see him go back to the Night's Watch and ask them to make the sacrifice so that way they can really slow down the NK and White Walkers and buy more time for Jon/the North.
