It seemed less that he was waiting for the right moment to kill Locke, and more like a sudden change of plan upon learning that Locke knew of Eloise. For some reason, Ben really didn't want Locke to find her. I mean, when we see Ben and Eloise together later, there's no hint of, "Damnit, how did HE find me?" She seems perfectly fine with Ben knowing where she is.

That's why I'm so interested to figure out how Locke found out about her. Who gave him knowledge that Ben didn't want him to have?
