It's possible that the Clare-Destroyer vs Priscilla battle has already concluded...
and Deneve, Helen, Yuma, Cynthia, and Dietrich have returned to Rabona, only to find that it too is under attack by the Organization... and that Miria is seemingly dead...
Deneve's and Helen's comments about Clare... could be denial... maybe Clare's dead (killed by Priscilla) ... or maybe Clare is now just a monster (presumably having to have killed Priscilla)... rampaging in the west...
------------------------------------------------------------
I love Yagi, BOTH Miria's and Clare's fates are unknown! Two of the most favorite/main characters, could possibly both been removed from the manga... grins... talk about a twist of plot! who would've ever thought Clare to be in the situation she is, as this Clare-Destroyer in an epic battle against Priscilla, or maybe even dead or stuck as a monster, and Miria possibly being dead too!
