Revenge or Redemption?

Payback

Yorktown: y...you're alive, how?

Enterprise: long story. Why did you do it

Yorktown: Idk I wasn't thinking straight, my memories of everything are vague and blurry

Then enterprise sees a vision revealing the sirens were behind it all, then realized this was from cameraman's perspective?

Enterprise: the sirens there behind all this they brainwashed everyone into believing that stupid lie

Yorktowns expression then got mad and serious then she dragged her sister outside.

When enterprise was pulled to the dock she looked up to see Yorktown had her rigging on.

Yorktown: you wanted revenge, let's give the sirens payback they'll never forget.

Enterprise: heh I couldn't have said that better myself.

At the sirens main stronghold in the Bermuda Triangle the 2 carrier's pulverized every siren in sight basically in some innate rage mode. Then finally they find the device that caused the whole fiasco in the first place. A black box that controlled KAN-SEN

Yorktown picked it up then handed it to enterprise

Yorktown: care to do the honors

Enterprise drops the box on the ground and destroyed it with her bow then scattered what was left in the waves.

The 2 then headed home preparing to explain Enty being alive to everyone in the morning.
