Actually, Nalia's first assumption when she sees the Exia will be that it is a Celestial Being pilot/Gundam Meister, and she will probably try to shoot it down. As a reminder, Saturnalia is originally part of Ribbons Almark's group, the bad guys from Gundam 00, and will consider the Exia an enemy. The reason she has the Virtue in her possession is because it was stolen/salvaged/refurbished. it will be interesting to have both Reve and Nalia working together in the same ship, but Nalia might not be the best person to convince Reve to join.
