Betrothed

Starfire reveals that she is actually the princess of her home world, Tamaran. Starfire has been called home by 'The Grand Ruler of Tamaran', only to discover that the new Grand Ruler is actually Starfire's evil older sister, Blackfire, who orders that either Starfire marry a hideous alien or else his army will destroy Tamaran. Robin is upset by the fact that Starfire is prepared to marry someone who she has never met. Robin tries to get Starfire to run away with him, so he climbs Starfire's balcony and tries to talk her out of the marriage to no avail.
