In 2374, according to Lasaran, "The Vorta advisor here is getting suspicious" that someone there was an Federationinformant. He continued that, he was "Asking questions. Making a lot of "routine" security checks in my section," forcing Lasaran to believe that he was soon to be discovered, and wished to defect to the Federation. (DS9: "Change of Heart")
In late 2375, the Female Changeling ordered that their work be documented and to then have them eliminated after not finding a cure, before further requesting that Weyoun activate their clones, hoping for a "fresh perspective". (DS9: "Penumbra")
In "The Dogs of War" he was referred to in the script as a "N.D. Vorta".
The costume worn by Major in "What You Leave Behind" was originally made for wear by Iggy Pop as Yelgrun in "The Magnificent Ferengi", but Pop ended up wearing a different costume in that episode than intended. Two of the costumes themselves were later sold off in the It's A Wrap! sale and auction for US$665.00 and $1,224.99, respectively, and still featured name tags reading "Iggy pop".
