I thought this story recap was pretty funny and it doesn't even cover all the bullshits
So we spend the first act with Grace being put "to test" by Gideon in the care center going through a series of dangerous events and antagonizing her only for it to be revealed that they actually be revealed that they needed her ALIVE and willing to cooperate the whole time.
Then the second act Grace willingly cooperates with Wesker, sorry, Zeno, who looks like Wesker, which at this point is well documented to be a worldwide villain (she would know, being in the FBI and her mother being Alyssa) and the guy who had her mother killed without any actual story reason.
And in the third act, Leon and Grace nearly die jumping out of the Elpis platform to scape Zeno only for it to be revealed in the very next cutscene that the objective is to get back to Zeno, who's been standing there still the whole time we assume.
Zeno gets taken out without any explanation why he looks, acts and exhibits the same powers as Wesker. Gideon comes back saying "oh I must had it wrong the whole time anyway yes now my objective is to spread the antiviral even if I just learned of its existence 2 seconds ago". Then, boom, Nemesis.
"Redfield has a message for you" the message being "man I couldn't care less about any of the shit that happened in RC or to you specifically, sending out my RE8 NPCs while I skip this one".
And by the way Spencer was so kind the whole time, we just never knew.
This is some fallout 3 type of shit
