If anybody had told me after Kotor1, that I would ever voluntarily take the portable drinks tray along outside the Ebon Hawk again, I would have said they were crazy.
I now stand corrected.
It is the one and only T3 - "I'll be back!" Terminator on wheels
Forget the T1000 and the Terminatrix, T3 with the right equipment makes a scrapheap out of them.
Kreia was the decoy, T3 was the one manipulating everything from the beginning, pulling the strings, arranging the voice locked navigation system and all.
Funny dialogue, part of the story, carries his own weight in conflicts, what more could one wish from a droid ?
