David's robot toy companion. He is unable to tell lies and helps to guide both David and Monica, despite not understanding either of their situations. His knowledge is limited and his personality is simplistic, but Monica finds Teddy easier to communicate with than David. This could be for a number of reasons, including the possibility that Monica is not used to dealing with a robot that acts human, and Teddy does not provide this feature. He only speaks when spoken to, and seeks to comfort always.
