Teen Titans

S01E02 Sisters

A strange alien probe arrives to take Starfire away, leaving her puzzled about its intentions. Meanwhile, Starfire's sister, Blackfire, drops in for a visit, and Starfire finds herself hoping she would just go. Blackfire is everything Starfire isn't—exciting, trendy, and carefree. The other Titans seem to be enamored with Blackfire, making Starfire worry that they might prefer her sister over her, leading to fears that she could become unnecessary.
