User blog:GWAINE/Possible to happen in series 5

Since it's my first time I would apreciate your understanding about wrongs I might do.I would like to inform you that english is my second language and my english level is FCE. I write my thoughts about what might happen in series 5. These are some of my thoughts about series 5. I hope you find my blog interesting and enjoy reading. I tried my best and I accept every friendly advise that can make me better.
 * First of all, it is possible for Arthur to learn finally that Merlin is a sorcerer, the most important moment of all Tumblr_m1amduBO4g1r0z669o2_r1_500.jpgs in my opinion.
 * Secondly, series 5 may contain a battle between Aithusa and Kilgharrah, the first dragon battle in series.
 * A fight between Morgana and Arthur is possible, if Morgana has all her powers things will be difficult for Arthur.
 * Also a fight betwen Mordred and Merlin is possible, Morded has warned that he wil revenge Merlin.
