Reen is already fighting, and with the shield he parishes the Darth
while injuring the two others guys.
The man under the net with Obi-Wan is uncounscious, maybe Obi-Wan hit
him, you pull his ligthsaber away. But the guy you fighted first
starts to awake.
You send the shield to Reen, and go to free Obi-Wan:
Maybe you could escape in the Darth's ship ???
