While he was still put off by some mysterious leader of a cult. He could not deny, having people in his force who could deal with Morgana, more so than anyone else apparently, would be fortuitous. He would just have to keep an eye on them. It might be possible that they could give him the information he needed to deal with Morgana, then he can deal with the cult properly. Because everyone knows that cults were fanatical and hard to control. No matter how much they claim they would help his movement.
