That's a vague answer. Bruce wonders why Sevika would choose not to specify a name. He imagines they're likely not from the same universe. Or if they are, she's very much from a different planet. So why the evasiveness? Not that Bruce has been terribly forthcoming with information either (he did just refuse to confirm his age). But it's different when Bruce is cagey. When others do it, it just makes him curious.

"Was it built that way? Or did something happen to cause it?"
