To stop Jacob from killing Emma, you must prevent Jacob from becoming infected.
The Threat: Jacob's Infection and Emma's Fate
Jacob will only kill Emma in Chapter 10 if he is infected when they reunite. This specific scenario is the last way Emma can die in the game if she has survived all prior events. The key to preventing this tragic outcome lies solely in preventing Jacob from acquiring the infection.
Preventing Jacob's Infection: The Crucial Moment
The most critical moment to ensure Jacob remains uninfected is during Chapter Six. If Jacob avoids being bitten and infected in this chapter, he will not become a threat to Emma later in the game.
Here’s what you need to do to prevent Jacob's infection:
- Chapter Six Action: When playing as Jacob in Chapter Six, you will encounter a challenging moment that requires quick reflexes.
- Successful Quick Time Event (QTE): Jacob must successfully dodge an attack during a specific Quick Time Event.
- Avoid the Bite: Successfully performing this dodge will prevent Jacob from suffering a neck bite, thus keeping him uninfected.
- Consequence of Failure: Failing this QTE will result in Jacob getting bitten and becoming infected, which directly leads to the possibility of him killing Emma in Chapter 10 if she is still alive and uninfected.
Ensuring Emma's Overall Survival
It's important to note that for Jacob to even have the chance to kill Emma in Chapter 10, Emma herself must survive all previous chapters and remain uninfected. For instance, you must ensure Emma does not get infected in Chapter Four. If Emma dies before Chapter 10 or becomes infected herself, the scenario of Jacob killing her due to his infection will not occur. Therefore, her general survival and uninfected status are prerequisites for this specific death to be possible.
