Celestine asks " Yeah..", Levi handed her a transparent tablet, " here", he said pointing at the screen. " The shield that Cascade made around it is the same with what surrounds their castle and the Keeper's mount.", he explains. " You had broken that shield before right? the one in the castle? " " Yeah" " I think...you can break that's in the site" Levi suggested. " Hmm..", Celestine nods , " but I think it would be better if Vex will do it for us?", she said. " Vex?" " yeah..he's the one who put up a shield in the glass hall before right? He can build and destroy" Celestine said. " and if he does that...we can break them both...the dad and the son", Levi mutters smiling
