When the resident of Megaton looks to RobCo Industries to furnish them with the finest in mechanized butlers, one admirable choice is the Wadsworth model. With the latest in hair-cutting and "humor array" technologies (sample quip: "War does not determine who is right; only who is left"), and the ability to keep a home looking shipshape and almost presentable, the Lone Wanderer's metallic pal is fun to be with.
He may give instructions on how to spruce up the player character's house, directing them to Craterside Supply.
He may restyle haircuts.
He can tell jokes (only once per day, so he can recharge his 'humor emitter array').
He can give the player character purified water, but only five at a time before needing to refresh his supply. It takes the regular 3 days for him to refill his supply (meaning he can restore 100 HP every 3 days).
If the player character had not purchased the infirmary, and are moderately injured, he will state they are not looking well. For more severe injuries he will say they appear to be injured, and suggest that they seek medical attention as soon as possible.

Also, if the player is crouched while wearing the Chinese stealth armor, or gets their haircut with a Stealth Boy active, nothing will appear where the players face would be.
