Useless continue explaining about Raven's background in a fast pace to its Master. It learned that if he explain about some information in short and fast, it's Master might not skip.
[As for her character and personality, she's more of a survivor—]
'Gold digger?' Eren interrupted lazily.
[W-what? No, no, she's a rogue mercenary type—someone who does whatever it takes to live and stay comfortable—]
'Like a gold digger, right?' he cut in again.
Useless paused, clearly exasperated by it's Master's words.
[…Master, I think you're misusing–I mean exaggerating that term—]
'Answer me this. Does she live for money?' Eren asked dryly.
[Uhh… well, yes. She does. She likes money, needs it—]
'Then she is a gold digger.'
[.....]
There was a long silence in the mental space. Useless sighed in defeat.
[Yes, Master. She's a gold digger.]
Of course, Eren's definition wasn't entirely accurate—but he wasn't wrong either.
