Cv2 Incursions
Have you ever wondered why all the Revenant companions you have Incursions with always react with terror as it first happens, despite it never having any negative effects on you? Have you, maybe, heard them list statistics on how deadly it is but assumed this was just another bullshit protagonist power and moved on? Fun fact, Cv2's lore goes deep and is full of internally consistent logic, and there IS a logical explination for this.
In the lore, incursions ARE a scary prospect. While far from common, they are a biproduct of jail malfunction; in essence, they are like when you start to choke while drinking, when the water "goes down the wrong tube" and enters your lungs. Jails seperate the Ichor (Revenent blood, gold) from your human blood, giving you the stolen Ichor as a resorce to burn for forma and regulating live, healthy Ichor from your active partner. An incursion is when your jail does an oopsie and accidently lets the backflow of hot, piping Ichor from your partner flood your fragile human heart. The early revenant hunters tried this, and it... does not take. Statistically most incursions result in death and even those which don't, can seriously hamper or disable a hunter for life; Ichor is a REALLY powerful and insense substance and the human heart is not built to take it. The worst part of this between trusted partners is how personal it is. Can you imagine losing your brother-in-arms because YOUR blood stopped his heart? It's so violating, for both parties involved.
But why then, you ask, can our character take this like a champ? Is it because we're just oh so special and so the rules don't apply to us? KIND OF. But far from being unexplained, this lies in a detail given to us in the begining of the game but oft forgotten; we are not pure human anymore. Thanks to the ritual, Lou has given us half of her revenant heart and baby, it thrives on Ichor still. Meaning when we experince an incursion, instead of being flooded with a deadly liquid, we instead just... get more blood. The ability to pervice memory vestiges, that... I am less clear on. But I think given how internally consistent everything else in the game is, I make a guess that in fact, this is something all revenants are capable of, not that they have tried it; that if they grant their blood willingly to one another directly like with a Jail, they could view each other's memories and even experince the latent regrets of other characters entirely. It may be a subsect of Lou's time powers as well, I'm more open to feedback on this one.
