I think there was a lot of incompetence to go around.
The idea of Sebastian as a field agent is just dumb. He proved that again in this episode and nearly got himself killed.
If your agent is going to the 10th floor for a meet, follow her up so you can get into the room quickly. Have more than one guy on perimeter security.
If you're searching a 30 story building, get some help.
GPS does not work on a horizontal plane as shown. They'd know what building, but not what floor.
Why couldn't they track Torres' phone? It was on the whole time, they called it.
It was neat to see Cady from Longmire though.
