My thoughts of RE9 trailer 4

Just my hot take on the RE9 trailer 4.....when Sherry says 'we are running out of time' she literally means her and Leon. Grace was taken because she was conceived prior the the events of RE:Outbreak, so Alyssa was pregnant during the outbreak, and gave her immunity to whatever the survivours all have.

The larger mutated monsters we're seeing ARE the survivors of Raccoon City. We'll encounter 6 of them, like the trailer says.

The others want Grace because of her immunity and chance to reverse it. End of an act, Grace and Leon will both learn this, and find they need to go to an under ground lab in Raccoon City to synthesis a cure for Leon and Sherry. It fits in with Graces gameplay in synthesising drugs to kill zombies.
