Wow. So Ben tries to bluff his way through keeping his own daughter from getting killed and loses the bet - so now he's going to hunt down Penny.
("Changing the rules" I presume is some code for an unwritten agreement with Widmore not to kill the other's immediate family)
And Ben obviously has a way to summon the Smoke Monster (so why is he then so afraid Widmore's guys can take over the island?)
So does this mean Ben will eventually hire Sayid to kill Penny (in "The Economist", he's already shown a willingness to kill women) only to be opposed by Desmond?
