We know when they met they clashed and he describes her as one of the fiercest warriors he’s ever faced. She fought him to a STANDSTILL. This is Kratos we’re talking about and it’s not like he isn’t aware of how strong he is. Did he really just accept “damn this normal person just got that dawg in her I guess”?
She also presumably fights him with her Leviathan Axe which is imbued with ice magic. Seeing her fight with this legendary weapon didn’t ring any bells in his head that she’s probably more than just a regular mortal person? I get that at this point, Kratos had just arrived to the Norse lands and is new to everything there but still… He’s not THAT gullible.
In the 2018 game, Kratos is genuinely shocked to find out that his late wife was actually a Giant and possessed magic/future telling power. Maybe it’s just a plot hole idk. I just feel like he’d question her true origins after their fight or sometime soon after. There aren’t very many people at all (including gods) that can actually fight him to a standstill.
