How do we know what info Richard has shared with the other Others? How do we know what the other Other's, like Ben, learned independently of Richard? I'm just saying the fact that Ben knows how to summon Smokey might not be known to Richard and Ben might have learned it some other way than Richard teling him. And as far as we know, when Ben summoned Smokey to take out the A-Team, that might have been the first time he ever did it, so Richard wouldn't necessarily even know that Ben knew how.
Heck, Richard's idea of summoning Smokey seems to be to shout out for him whenever he feels like it.
If you shout out in the middle of the jungle, and there's no one there to hear it, was there a noise???
