After the Aurora's crash, Keen was ordered by Captain Hollister to send a message to all the other Aurora survivors. However, only he and CTO Yu made it. After the two met up, Yu wanted to search for more survivors, for which Keen denied. His demise is unknown, however it is suggested that he either fell off the island or got eaten by Cave Crawlers.
