"Astromech," Matt repeats the word softly, running through his mind to see if he recognizes the word at all. At the moment? It's looking like a no, but he's able to make an assumption on what he does know. Astro: Space. Mech: A piloted robot. What? That doesn't seem right, especially not if he's autonomous. Reroll on that one. Astro, space... Mech... Mechanical? Redundant, obvious... Mechanic? Maybe.

BB-8 seems a little... Round and unassuming for that purpose, but he won't say that out loud.

"He's got a personality, at least. Do you understand all that?"
