Of course I think we would all agree here, but as HB has said, he doesn't see anything wrong with this girl, just that his friend seems to be moving too quickly.
I will agree that when you know, you know. So maybe he just knows.
To second what CE said though, even if someone had said something, he isn't going to listen. You simply don't know, nor will you ever know, how he feels or how they are together aside from when you are also with them, which given that they live together, is less than 1% of the time they are together.
