Reg

Reg is a Mister Handy found at the General Atomics Galleria. He can be found inside the Fallon's department store.

Effects of player's actions
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 you can defend yourself without any repercussions.

Other interactions
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 them that they shouldn't touch anything.

Appearances
Reg only appears in Fallout 4.
