This is quite likely true. (And oh, dinner. Thank the Force for mothers).

Axis will likely explain what they figured out to Talia while John gets the swoop back into the Hawk's garage. He will certainly NOT mention how they obtained their information, but will advise her to be cautious for at least a couple weeks - he figures they did a bang-up job covering their tracks, but thinks that careful is the best way to do this anyway.
