I take "eye" and "tree" as resembling an ent, an alive tree. Marie Curie portrays an ent in the anglepod's bathroom. Unfortunately she's really bad at painting, and her portrait resembles more a Christmas tree. The Eye of Providence enters and, just from the shape of the Christmas Tree, instantly recognizes its own portrait. The Eye of Providence asks Marie Curie how much she wants to have for the painting, but Marie Curie just wonders if the Eye of Providence is made from Radium, because it radiates so much.
