Red vs Blue: The New Kid
In the past, North introduces his new A.I., Theta, to York, Washington and South. Theta exhibits a childlike, shy personality, so York introduces his A.I., Delta, to help Theta with its shyness. When North introduces Theta to his sister South, Theta mentions that he also has many brothers and sisters. The Director arrives, to prepare a test for Theta and North. He reminds Delta that protocol forbids direct interaction between A.I.s, then orders it to administrate the test.
