Garcia called Prentiss and Morgan got called by Gideon. They both, however, got the same exact message "We found the building, get going!" All of the units, including half of the police force (the other half was going to take down Henry) and all of the BAU, arrived at the building at the same time.
The BAU team went downstairs while the police cleared the rest of the building. Gideon was the first to go in to the room. He took out his knife and cut the ropes restraining JJ as Morgan cut the ropes restraining Hotch. Both of them had passed out because of the extreme stress of being kidnapped. Paramedics covered them with blankets, put them on stretchers, and then brought to the hospital, just to be safe.
Meanwhile, back at the mall, the police had to shoot Henry as when they came in to the food court he grabbed his shotgun from under the counter. They took him down without hurting a civilian, which made them proud of their work. It was a happy couple of hours for a lot of people.
The whole BAU had had a conversation with Hotch and JJ but were told by the nurse that they should probably leave so they could get some rest. They funneled out one by one and Gideon was the last to leave. Before he left though, he turned around, let out a huge smile, and said, "Why in the hell were you two naked?"
