Is Atreus Kratos Real Son

In god of war kratos and his son atreus are traveling across the nine realms to fulfill the final wishes of atreus mother faye.
Is atreus kratos real son. Kratos calls him boy the whole game not son. Also do we really know the kid is kratos son. To the jötnar he is known as loki. He is the son of pelops and hippodamia.
Atreus was conceived between the greek demigod turned god of war kratos and a jötunn named laufey whom he called faye. That would explain several things. So no kratos son won t die in the beggining of the game sending kratos on a rampage. Kratos catches a glimpse of a part of the mural atreus doesn t see that seems to depict kratos death at the hands of his son.
The real reason is that cory took forever to come up with a name for boy. First let s assume that atreus really is kratos s biological son. Atreus and kratos reach the top of the mountain and scatter faye s ashes together as son and father. Loosely based on myth atreus is kratos son they ve just changed some of the myth around.
As the two make the trek down the mountain atreus muses about his status as part giant god and mortal. It s only when he begins to get closer to atreus that he calls him by name or son more. Let s state the facts guys. Cory barlog stated that you play as kratos the whole game and his son will tag along for the journey.
Atreus is the son of kratos and laufey and the deuteragonist of god of war 2018. While pelops himself does not seem to be similar to kratos it will be interesting to see how kratos past is reflected through atreus. Eventually they came up with atreus and the story behind it and it just worked with boy as an emotional thing. There s just one thing that stumps him and it goes back to what he read on the walls.
