Taylor is in the outdoor cage when Zira and Cornelius walk up. Taylor starts to write a message in the dirt that says "I CAN WRITE". There is a closeup of him as he finishes, then the angle changes and he's still writing. Nova starts to erase the message and another human starts to fight with Taylor. You can plainly see that the whole message has been obliterated, but Dr. Zaius walks by a few seconds later and sees the word "WRITE" still imprinted in the dirt.
