Jaara figured it out, he wanted to build another droid, but one that was usefull for combat and skills such as repair and computers. The droid would also make a good companion for JA-T1.
He needed scrap parts though, and there didn't seem to be any scraps on the Black Falcon. He opened all of the cargo supplies, only food and liquids were in the containers.
Jaara exited the cargo hold and entered the garage, but still no parts worthy to be made of a droid. Until he found the parts, he couldn't make a combat droid to aid them on the quest.
Side-quest: In order to make a combat droid, Jaara will need the right droid parts. Perhaps when the Black Falcon reaches Asthor, the crew could look for parts there.
