Fast forward to Ragnarƶk, 20 year old Berenice as a Valkyrie has returned to save Atreus while at the same time, criticizes Kratos for driving away his own child, again. She is willing to work together with him just for Atreus' sake, but if he wants to rekindle their relationship she has three conditions.
Berenice: If you want to make things up going forward, I have three conditions that you will follow without question. One, you will tell me everything. I am not going to tolerate being kept out of the dark. Especially if it involves Atreus and the Aesir! No lies and no bullshitting the truth! Two, I do things MY way. If I have to work together with you to accomplish our shared goals, I will do it, but I am working WITH you, NOT for you! I am also not going to have you criticize how I work or fight. If you also grab or shout at me like you did 3 years ago, we are done. For good. I will also not hesitate to go through you if you try to stop me from accomplishing my goal. And three, if ANYTHING happens in regards to Atreus, if he is found, captured, injured, or even killed, you tell me first! Understood?
