Damien could only watch helplessly.
It shouldn't have gone this way.
He killed the Strength Lord and he killed the Venom Lord. He gained power from them and approached in time to help with the battle with the Marionette Lord.
So why…?
Why did Iris have to do that?!
He saw it from the top of a faraway mountain. The moment when she made that decision, he rushed without a single thought in his head.
The only thing he could do was try to push forward.
But it didn't work.
Despite all odds, it didn't work.
He wasn't just teleporting. He used Flash Step to move forward in space and backward in time, so by all logic, the movement should've undone itself by the time he got there and he should've had the opportunity to save Iris and fight together.
But it was futile.
No matter how far back he went in time, their movements didn't change.
