May be too wordy, but something like, “He’s in much better shape than when I found him.”
Maybe like this for the full line since it is mostly all off-screen:
“Come on, I’ll show you Threepio. I fixed him up. He’s way better now. Watch.”
turns Threepio on
EDIT: I see what you mean. Watched the full unaltered scene. This could work:
- Ani: “Come on, I’ll show you Threepio. I brought him home.” removes cloak covering him “I’m fixing him up. He’s way better now.”
- Padme: “He’s wonderful.”
- Ani: “You really like him? He’s a protocol droid to help mom. Watch.” turns Threepio on
