Renard's Confidant warned Sean Renard of information regarding the Royal Families and Renard's Canton. He was familiar enough with Renard to address him by his first name. He operates out of Vienna, Austria, but has a French accent while speaking English.

The confidant telephoned Renard to tell him that the family had sent a Nuckelavee to Portland to get Nick's Key.

The confidant telephoned again to tell Renard that he had emailed a file about the Nuckelavee.

Renard called him while he was driving around Vienna. The confident answered his phone in French. Renard asked him if the Royal Family had sent a Grimm of the brutal group, to which Renard's Confidant said he didn't know.
