Rexy goes to get the deer carcass.
But the Scorpius Rex enters and roars.
Owen says " Yeah I have no idea what that thing is ".
The hybrid swings it's tail full of its dangerous quills. But it hears a sound of a Dreadnaughtus and decides to follow that instead.
Biosyn Valley begins to burn down. But all the Scorpius Rex can do is look at it.
It finds the group.

Claire says " Doctor Wu's first dinosaur hybrid which was never put on display, the Scorpius Rex". It swallows a flaming locust whole.
Ian Malcolm tries to distract with a flaming locust on a stick. All the Scorpius Rex can do is keep looking at the flame. Malcom tosses it and throws it far away. The Scorpius Rex follows it.
The final battle happens but another fighter approaches another Scorpius Rex. It goes after the Iguanodon and than leaps onto a Dreadnaughtus using its quills on it. It falls down nearly crushing the group of people. It goes after the Therizinosaurus and brings it down. Rexy decides to leave the Biosyn arena to avoid getting killed. Both Scorpius Rex roar at each other across the Open area.
Doctor Grant says " This isn't about us. It's about them".
Both hybrids keep fighting each other. But in the tussle one of the quills hits Doctor Wu.
As the group leaves the area. The hybrids keep fighting but a large column shatters behind them and falls on top of the two savage hybrids. A poetic ending to the new cloned variants of the same hybrid that met its end on Isla Nublar.
