He waited until he could hear Gibbs exit on the upper floor before he cast a quick spell to check how many heat signatures there were in Autopsy. The spell didn’t let off any colors but instead created a piece of parchment that showed the results. Tony knew it was a risk to do so with the radio on him and cameras in the stairwell, the magic may interfere with the technology and cause it to short out. However, it was worth the risk to get a better idea of the situation. His spell registered and listed four heat signatures. Since he didn’t move about he couldn’t get a 3D view of the other room and thus didn’t know if there were others behind the four signatures. It would typically show up as a hotter signature, but not always. So he could be fairly confident there were just four living in the room, plus Qassam’s dead body, but he couldn’t know for certain. A movement at the window drew his attention from the results.
