Rean, Kentucky, Celis and the others also returned to the Divine Military Academy before and after Roan got there, as they had different missions. The same went for Foliana and the rest.
It goes without saying that those who tried to get rid of the twins and Kentucky obviously noticed that all their attempts failed. The weird thing was that nothing was told in the reports, as if the attempts never happened.
They weren't idiots. They knew someone was behind those failures, and that the twins' group was being observed. That being the case, whoever tried to target the twins' group, or the various powers in this case, would definitely not try it again anytime soon. If information escapes somehow, they would be the ones on the back foot.
