Hmm...there's been no suspicious activity at all. I find that highly suspicious.
Sorry, no time to talk! A guard must always be on duty!
You can let Dengard know I'm watching everyone more closely, as ordered. Yep, I live to serve Pandaemonium! No need to tell Dengard any different.
But...hey...you've held me up too long with idle chatter! I have important guarding to do!
