Analysis
John wipes away more sleet and uncovers the epitaphs. He sees they are from Angela, Frank, and Newt in tribute to their mother Emily (though Newt’s is just an imprint of his infant hand). John discovers that Dr. Hoenikker’s memorial is actually nearby, and is just a “marble cube forty centimetres on each side.”
