Kate, on the other hand, doesn't know when to keep her mouth shut and she's curious. "Steve breaks that rule all the time, doesn't he?" she asks, although Steve isn't the one training her. "I mean, I'm not asking in like a 'Steve does it, so why can't I?' kind of way, I'm just curious." And she's curious as to why he does it. She knows he's not a cop, not in the same way Danny is, but they've worked together back home.

"Have you ever done something like that?" she asks, pushing on. "Gone on without backup?" Maybe there's a reason he's trying to instill this in her so firmly. Maybe it's a really good reason, too.
