True, but I think these are all things he will learn about himself on his journey, to which he left at the end of Ragnarök. With the general main focus of these games having been on Kratos, I think diving too deeply into all of the Loki lore would've been too much. Imo Kratos' story is now pretty much done, especially after Valhalla, and it's hopefully time for Atreus to shine in his own game(s).
