Communicating panic and lack of control to your passengers is never safe. You will be absolutely honest and clear with ATC and any escorts/emergency vehicles regarding your current status, but you cannot ever let that bleed into your communications with the passengers. In all communication with passengers, you need to be about as calm as if you're just taking a walk in the park. "Folks, we're making an unexpected detour to check out some technical issues that came up. We might be delayed a few hours, but the ground crew will book you on the next flight available, and work with you on rescheduling your transfers."
