You find a suitably windowless hallway inside a nearby building. You duck in as the first bombs start exploding.

"Hello, Tetras."

"Remember us?"

"....No."

"Take a good long look."

"We're sure it'll come back to you."

You take a look at their signs, trying yo puzzle together who they are.

Oh, wait a minute.

"No.... No, wait! I killed you!"

"Back from the dead, snakelady."

"It's only fitting that we'd beat you..."

"...In ROUND TWO."

This is slightly terrifying.
