Wolf probaly will get f**ked up bad by the PredAlien. We already saw him getting impaled by the PredAliens tail so ....
Maybe he janks it out and both of them retreat. The Predator runs back into the forrest and the PredAlien returns to her Hive in order to recover ( get the Wristblades removed ) from the wound Wolf gave her. The Predator on his turn sits high up in a tree, oozing blood badly! He janks out the tail and lets out a massive roar. He gets his med-kit and stuffs the wound with almost the same substance we saw in Predator 2 ( only this time it is created using forrest materials
) Wolf readies himself and heads back to the location only to discover the Predalien Queen has disappeared. He goes back into the Hospital and noticed her.
And thats where it ends for me... at the end I wrote the part should come up with the girl being pinned to the wall... The PredAlien running from the Predator and the Aliens getting decapitated. Although I dont think it'll happen ( cause we saw Wolf standing in the Hive with NO chest-wound ). Oh well, it never hurts to speculate.
