Ragnar dreaming about Athelstan and treat the seer with snake when he learn Athelstan is with Ecbert.
Ragnar is agressive toward everybody without Athelstan in Mercia .
Meanwhile floki shut your face.

Athelstan's journal : Our little sweet man must chose his love for his god or his love for a another soul on earth . No this si not Judith but Ragnar in episode 6 when Athelstan become christian again . Even god can't seperate Their bond .
Athelstan reborn again as christian but died after that . Ragnar reborn again after Athelstan's death , letting a part of him dies.
The seer said only the dead ( les morts in french ) will take Paris . It was Ragnar pretending to be dead wearing Athelstan's cross ( Athelstan represesent the cross..) Athelstan also took Paris as really dead.

Ragnar become mad when he throw old treasure from lindisfarme to peasents planning to go to wessex. He think about his most precious lost treasure .
Ragnar gave Athelstan's cross to Alfred not for religion but for love .He gave also Athesltan 's arm ring to Ivar . He wanted so many Athelstan's legacy .
At last , Athelstan's body rest in Kattegat where Ragnar was born .
Ragnar 's body" rest" in Northumbria where Athelstan was born .
No Aelle even your own god ( and Athelstan ) won't help your army . You killed someone very precious...
The last memories of Ragnar : It was only with Athelstan there was not bad memories.
Athelstan's holy spirit was in Ragnar when he died to comfort him and maybe take him to Valhalla. ( Athelstan's spirit is very omnipresent and powerful even in the last 2 season without George.)
So maybe i'm wrong about want i said mostly in the end but i like to see it that way . So please respect.
