<p>The fact that Aria is inside the dragon is not a bad theory I find it interesting
</p><p>Aiz does not have Bell only for the sake of his power, but his way of acting his kindness, his purity, his honesty are also part of Ais's interest, as Rigel31415 said above his Larias freese le owes that to a person, Bell constantly thinks of his objective, to be hero and to be with Ais he will not be able to allow himself to die before having fulfilled his objective pushed by his exeptinel competence, Aiz is the heroine of Bell and Bell will become Aiz's hero like Albert was for Aria, it is clear that she does not understand her feelings for Bell because she never experienced these feelings there but in a fairly intense moment or Bell will be in danger death, or Aiz would be exposed to certain danger of death or Bell will make her heroic appearance and protect her, I have a very good chance of believing that they will share moments together or their relationship will develop as quickly as Larias freese, before the final battle, and Bell will have twice as much feelings for Aiz and will fight BDOE with incredible growth force, he will fight with all his soul desiring to give back to Aiz what was stolen from him, of course there will be a moment of despair during the fight there will be dead, that's for sure, but there will surely be a combined attack from Aiz and Bell together, or a skill gained by fighting with Aiz, or else combined the two attacks The argo vesta and the Lil rafaga , a devastating attack, I also dare imagine that they will both be 8/9 level (the only ones from Oarario)
