Well, Vernietigen won't actually come back until the next story arc after Chaos Crisis.

However, Titans are allowed to interfere if it deals with the return of Vernietigen. Dromed would be allowed to intervene enough to help stop him as its a disaster that most Titans want to avert. It's the same reason why some Titans are helping GSSOC stop Vernietigen in the Milky Way.
