Okay, so when all the siblings moved out except Luther, who bought groceries? Not Grace, Diego said she was never allowed off the ground, and I would imagine Pogo going out and buying them would cause a little disturbance. I can't for the life of me imagine Reginald Hargreeves in a grocery store, and I'm having an equally hard time imagining Luther in one, but he seems like the most likely person to do it.
But like... now I'm imagining Luther in his super suit picking up eggs, and... idk. It just seems so off XD
