There's a hum, like she's taking all of this information in, not even bothering to ask more about the subjects he's being a little short about. Maybe she's picking up on the fact he doesn't necessarily want to say more about those.

Ange, are you calling him a friendless loser.. Girl!!!

Then again, it's more likely she doesn't necessarily mean it with any malice, since her tone doesn't contain any of that. The question is probably just accidentally worded a little too bluntly since Ange doesn't know how social nuance works half of the time..
