Reg

Reg is a mister handy found at the General Atomics Galleria. He can be found inside the Fallon's Department Store.

Interactions with the player character
Upon entering the store, he will tell the Sole Survivor that the store is in perfect order and that he has spent years working on getting it that way. He then tells the Sole Survivor that they shouldn't touch anything. If anything in the store is moved in any way by the player, Reg will become hostile and attack. At this point it seems that the player can defend themself without any repercussions
