Kratos' sanity VS Ariel's teenage years

After the events of GOW4, there is a slight lull in Kratos' life during which he begins to bond more deeply with his son. Lo and behold, a watery image appears from a brook the pair are drinking out of while hunting.

Atreus: "WOW! His beard is huge! Who is that?"

Kratos: "Your great uncle, Triton, ruler of the seas in his father's stead." *pulles out the Leviathan axe* "What business have you here, son of Poseidon?"

Triton: "Family business. And whether you want to admit it or not, we are family."

Atreus: "WAIT! Poseidon, as in the Poseidon [I]you [/I]killed?"

Triton: "Well, [I]yes[/I]."

Kratos: "That is [I]not [/I]something that I am proud of."

Triton: "Look Kratos, what you did in your youth cannot be undone. But you gave hope back to the world, and for that, I thank you. After father died I raised a family, and even settled a kingdom. So it was not all for nothing. But, I have a problem."

Kratos: "I will [I]not [/I]kill for you, Triton. Those days are over."

Triton: "I am not asking you to. You see I have seven daughters, and they hardly knew their mother. The youngest, well, she needs a guiding hand. And seeing how well you've done with your son, I thought you might be willing to at least start making up for the past."

Kratos: "Let us see her."

Triton: *summons a legged Ariel from the nearby bushes* "My youngest."

Atreus: "WHOA! Have you been starving her or something?! She's so skinny!"

Triton: "She takes after her mother. Kratos, if you do this, I will have to warn you. She can be quite a handful."

Kratos: "So was [I]my [/I]son after Faye left us. But look at him now."

Triton: "Kratos, I smell blood on him! The blood of a God!"

Kratos: "He was having a moment. But he has grown out of it."

Triton: "I...see. Well, if you will impart some wisdom and training to my daughter, I would be most grateful. Do what you must. But PLEASE reign her in, she's nearly destroyed the kingdom several times!"

Atreus: "whoa..."

Kratos: "As you said, she will be with family. It seems that it would be good for her to learn how things work outside the world you built."

And just like that, a young Ariel takes on the alias "Girl," and begins to live, learn and train under the stern eye of the former God of War(and Father of the Year.)
