[Another short visitor! Supreme Kai of Time watched the video on her journal with stars in her eyes. Robots. Now she's in the shop, somehow able to make her way straight to dum-e and examine it. Let her have a look at that arm and the joints. Not to mention ask questions.]
So you're a mechanic? Can you build other robots? If I took your arm off, could you build a new one? Are you sentient? Ooh, can I have a look at your brain? Do you have a brain?
[Sorry, are there organics in this building she does not care to notice]
