What I'm imagining part of the ending will be like is that ladybug and chat noir have a huge battle with hock moth and hock moth would end up winning and would have their miraculous and every one will be angry and all that. then u know how Natalie is ill and has the same illness as Emily (Adrian's mom) then shell end up dying and hock moth would start to stress and break down and will decide to use the miraculous on her. then he will realise that nothing worked and it was all a waste of time then that's when ladybug and chat noir find his hiding spot and battle him again and he would get all angry because nothing worked like he thought it would and ladybug and chat would then capture his acuma and get him arrested then i don't know what comes next. :))
