1. Well, they're a Dark Guild specializes in assassination. So they must be hired by Isghar to kill the ranked Western Army officer during the Cabria War. I would love to see the Trinity Raven again after eight years later since they survived in the anime, a scene of them flying away from an exploding Tower of Heaven. 2. I mentioned his past role as a Lieutenant Colonel of the Gohra Army and his feat of annihilating the Blue Dragon Regiment. I dunno if the Gohra Army is either of Isghar's or Alvarez' and same goes for the Blue Dragon Regiment. Bluenote is more of a frontal one-man army than a spy. 3. That might be a possibility that Bisca immigrated to Fiore from the Western Continent because of the coup or rebellion that led to Alvarez' rise to power. She doesn't fit to be a spy anyway because of her time as a band that Erza was there to 'persuade' her to join Fairy Tail. :D 4. That counts too. Beth does look inconspicuous indeed. 5. The Cabria War is an event filled with questions and mysteries to find out in the future chapters of this manga.
