Encounter: Mad preacher with hostage and nukes
There is a man ("Wastelander") standing on the second floor of a building in an alleyway west of the Reilly's Rangers headquarters entrance (B). The alley has been rigged with mines and nukes that he detonates if you try to get close to him. There is a hostage (another Wastelander) on one end of the alley, who you can talk to. If you are looking at the mad preacher when he detonates, he waves at you. He also dies in the blast.

If your stealth is high enough, you can sneak through and pick up the Frag Mines (at least five) and multiple Mini Nukes (there are at least five; one behind and one in between the barrels by the slide, one next to the shopping cart, one on some rocks across from the shopping cart, and one on the merry-go-round. Even without the Light Step perk, the explosives will not detonate if you step on them, as they are intended to explode only when triggered by the preacher. Alternatively you can use Dogmeat to find ammo, to pick up the mininukes, or to find weapons, to pick up the Frag Mines.

If you remove all the nukes and mines off the ground, the Preacher can still cause detonation if he sees you in the alley. Removing all visible explosive doesn't stop him, there are at least five more Mini Nuke detonations. You can talk the hostage into confronting the man using Charisma, but he gets blown up in the mine field. Only other solution appears to be killing the preacher (sniping or a Frag Grenade from below, for instance).

Note

 * When the Mad Preacher yells "Trees! trees! to the north! But they're deadly, and they will be consumed by the GREAT FAT WORM!!!", he is referring to Oasis. He also appears to be in great pain yelling "The sun why does it burn? MAKE IT STOP!!".
 * He also talks about putting the sun in a glass jar, and "breaking it over ourselves" which could refer to the nuclear weapons used in the Great War
 * The preacher doesn't have anything be pickpocketed even if you could reach him. There is no trigger to be taken.
 * Neither of the characters have anything else than their clothes.
