Uh, just for Bennet, the last time we saw him, he was intent on Making EL keep his promise
Also, one of the Pixie mons is way too obvious for the voice. I have more Faith in this game than to believe it would be that straightforward. That said, I believe that starting from Ep 13, we are going to see shit hit the Rotom- F, as the Leaders are beginning to coordinate there efforts against Team Meteor, evidenced by the resistance in Calcenon. Furthermore, we now have Tabs on each of the Various Gem Keys, which means that Team meteor does too. Therefore, i believe it won't be long before we see those Doors scattered around reborn taking a more active role in the story
Also, has it been confirmed that the Temple thingurmajigger is behind the door beneath the grand stairway? cuz that's what the mapping suggests
