Lance lays on his back and notices his lightsaber is still activated. With one hand he deactivates it.
He looks up and sees Balek and Galder fighting. Once he's sure both men are occupied he looks around for an escape route. He sees one to his right and starts to get up.
Suddenly he stops. The pain is too extreme for him to take. He decides to start crawling. First he tucks his lightsaber into his tunic and then moves towards the opening and walks on his knees and his left hand.
He then remembers the droid that he saw shooting just before he fell to the ground.
After a short looking through his mind's eye he finds the droid and pushes him with a strong might.
With the little energy he has left he uses the force to start a relaxation technique and start the slow process of pushing the pain aside.
After he was sure the technique was going as planned he started off again.
