Louis is the cook/rec room Mr. Handy, there to help you acclimate to your new domestic skill set. He will assist in anything from food prep, to recipe ideas, to how to sew to repair your clothing. Louis is pleased to be helpful, but a little shy. He will also harbor slights and insults for a long time, so if you don't want burnt coffee for the rest of your vault stay, show a little courtesy. He can be found in the rec area.
