Just pull your friend aside and try to find a way to tell them what you want to talk to them about without it being obvious. If you find a time when you are alone with them, try to make up a word or phrase to let each other know you want to talk about NB stuff. You could say "Hey (whatever their name is), could I talk to you about pineapples (or whatever code word you choose lol)?"Just as a way to subtly communicate about that lol.
