Natasha nods, because that makes sense - planning to come back to strangers, to need to start over. In a way, she's glad it didn't happen that way, although every good thing seems to have its tradeoffs, in the end. Ideally, you just try to find a way for the pros to outweigh the cons.

She wonders if there's a mutual acquaintance requiring that particular modifier.
