While not *of* the Movement, there are many in Clan Giovanni who are sympathetic to their cause. More of them, of course, are more interested in turning a profit from their dealings with the Anarchs as the Movement fights their dual-front war against the Camarilla and the Sabbat.
The Giovanni are often feared for their reputed control of the dead, from ghosts and spectres. Politically, they skirt the issue of the Promise (Anarchs aren't Camarilla!) with that of the Treaty of Thornes (well, you see, the Camarilla says you're with them...) to attempt to get the best deals.
