Sybille asks "So, now that I know where he is, can I go deal with him once and for all?"
Your agent chuckles and tells her "Actually, we'll be providing you with some backup and equipment to make the mission go smoother." At this point the equipment (a laser pistol, a time stopper with appropriate goggles, and a teleporter beacon) are beamed in, packaged in a small box that your agent deftly snatches out of the air and passes to Sybille.
Sybille looks at the equipment and notes "I recognize the pistol from previous experience, and it's fairly obvious I'm supposed to wear the goggles, but I'm not sure what to do with this high-tech looking vest or weird hip-pack thing."
Your agent informs her "The vest is a time dilation unit, making the wearer have 4,000 seconds to do things in for an outside observer's single second. The goggles are to counteract some of the side effects related to the immense time dilation factor, and the hip pack is a teleporter beacon, which will transport you just south of the airport where you'll meet up with some other personnel who've been similarly equipped and also have prototype mind screens for field testing. You beam in 20 seconds if you push the switch on the teleporter to 'on'."
Sybille puts on the goggles, makes sure the vest is on right, properly secures the teleporter beacon, and flips the switch. The rest all happened in under a tenth of a second from an outside point of view, so you review recordings taken by one of the Joes sent on the mission. Sybille beamed in, there was a very brief round of introductions, and then they walked into the airport. They walked around all the security, making sure to dodge between individual frames in the security footage. When they got to Mauno they shot him several times with their laser pistols from several different angles, and then left before his head finished exploding.
There are now 28 Savants in the world.
