Who did Savitar Killed, Not Iris for Sure
Iris is Berry Allen's Fiance, And Savitar is a Time Remnant of Berry himself became evil speedster. Now Savitar's plan was to kill Iris West so Berry can be thrown into the Darkness for him to become Savitar (Thus Savitar is Born)
Now the people who watch the show knows HR Wells has a tech to change the face and voice (basically become duplicate of anyone), We also have seen in Episode 22, Berry AKA Flash using this tech in order to get passed into the Argus building to get
the alien power source.
But in the mean time since Savitar is Time Remnant of Berry himself he carries his face and tricked HR Wells to let him know where Iris is (on Earth 2).
So Savitar went to earth two and took Iris, where in the end we saw Savitar killing Iris and Berry AKA Flash couldn't save her. Now since Iris is an important character, I think Iris cannot be killed in the Show at least not now. So i have couple of Theories based on what i observed in the Show.
Also there was a picture leak for the finally show where we can see Iris Standing right there with Berry Allen
First Theory: Savitar Killed HR Wells
As we know HR Wells does have the tech, where he can become anyone he wants, Also HR was quite in guilt for letting Savitar know, where Iris is. So, This Iris can actually be HR Wells sacrificing himself in order to save Iris.
Second Theory: Savitar Killed Berry Allen
Since we saw Berry using HR Wells tech to change his face in order to get into the building, This can also be happen that Berry created another Time Remnant and changed his face to look like Iris in order to trick Savitar. As i think we learnt from the Show that you can make your Time Remnant, if you're will to Kill yourself.
Now i came up with the second theory because the final photo leak shows HR Wells as well but it can be Harrison Wells from Earth 2 as well.
What do you guys think, which theory makes more sense? or do you think that Real Iris West got Killed?
