Your son Atreus is asking who is it

You/Kratos: Boy, beneath the floor, NOW! Atreus: But..you told me to never go down there. Who is that? Whats he talking about? You/Kratos: I do not know. GET IN! Atreus goes beneath the floor where there is a small door

Unknown guy: Just tell me what i want to know. No need for this to get bloody!

Opens door

Unknown guy: Huh..Thought you'd be bigger, but you're definitely the one...a long way from home aren't you?

You/Kratos: What do you want?

Unknown guy: Oh, you already know the answer to that, hits you in the face
