Well all of that is going to be reported to Helene.

Levi honestly expects someone named Thief or Ninja considering the mysterious hooded guy he and Jean encountered but he supposes they must have been a smaller fish of some sort.

He'll also inquire about any additional details of the meeting -- not just what the baddies talked about, but maybe she heard or smelled or sensed anything odd, etc.

If that seems to be all that Margaret has to say, he'll thank her and then ask if there's anything they can do for her - he could assist if she wants to move on, or bring more peaches seeds to tend to, or see about arranging a teleport crystal if she'd like people to talk to more often, etc.
