Glitches / Easter Eggs
If you have Clover in your party, she gets mad when you "steal" this item, and goes rogue against you. On the PC version, if you use the "setownership 52392" console command, to just "take" the suit, instead of stealing it, Clover doesn't attack you. You can steal any other item from the room, and she doesn't seem to be bothered either, including the holotape.
