Do the members of the BoS recognise you or something after you complete Eyesight to the blind or Tend to your own buisness?

If you side with the BOS then you can make a peace treaty with the NCR if you're a Paladin.

And some of the BOS members do recognize you.

I don't know if you played Dead money so I won't spoil too much but you get some dialogue if you joined the BOS.

I played dead money, however not as an BoS member seems interresting though.
