The A.I. son of Monica and Henry Swinton. David struggles to feel accepted and loved by his mother, and rightly so, as she is devoid of most feelings for him. David's personality is similar to that of an average 5- to 10-year-old boy, as he is curious, slightly mischievous, and very loving towards Monica. Although David sees Teddy as a companion, he is also jealous that he is treated more as a son than David himself is. It is difficult to say how much of David's "feelings" are programmed, but the questioning of his own reality defines the character as more than an average android.
