Yeah, I can't see Jack letting Faraday and Charlotte mess around with poison gas (even if he went with them) when they're the only two people with protection against it. Earlier in the day/last episode, they admitted to keeping things from the survivors so who knows what else they're keeping things from him. And Jack must still have Ben's warning that if the freighter people come to the island that everyone on the island would die in the back of his mind. And if they asked Jack and he said no, Jack is going to keep his eye on them after that.
