- Charlie calls Panda "pumpkin" near the end of the episode implying that he could have romantic feelings towards Panda, but still confuses it with friendship.
- This is further reinforced when Ice Bear mentions he would not judge "out loud" upon seeing Panda in Charlie's embrace, and Panda being too tired to push him off.
- When Panda attempts to recreate the painting, he redraws Charlie based on many classic paintings: Girl with a Pearl Earring, The Birth of Venus, The Scream, The Son of Man, The Old Guitarist, and Van Gogh's self-portrait.
