Assume CR how? Like them knowing each other or like saying "oh they spend there days together doing things" if you're in a game together? Cause one is using what is canon (They are close, so of course they know each other) while the other is saying what the other character is doing.

Or like, having B know something about A that wasn't revealed to anyone ever? (Except via the plot, but B wasn't there for it. Either the reveal or when the thing happened) That would be infomodding then.
