"The speeder really looked amazing. Cobb said it runs on Spaceship fuel, and that we didn't have much of that here, so it needs a more efficient engine. Maybe everything that flies uses that kind of fuel to power up? I told him that his best option woudl be to chage it into something else to avoid having the fuel issue in the first place. "

And yes, Cobb had literally said 'Spaceship fuel', which Alberto had been confused by because back then he still had to see the ships in the Hangar. He already enjoyed speed and making up things with scrap before he got the engineering data point, it was kind of in his blood, and now he wanted to build ALL the things.

As for befriending Kaz...Alberto found the man intriguing and interesting all at once, and he had been talking to him like an actual adult instead of babying him. Of course, he liked Kaz.

"I know where the library is, but haven't visited yet. I'll have to see if I can meet him and ask about the vespa. Do you have a favorite color?" He looked at Kaz up and down and then added. "Black doesn't count."
