At Hanuman's command the monkeys build a funeral pyre and place the "corpse" on it.  The pyre is lit and the flames swiftly lick through the dry wood.  Up to this point Benyagai has played her part perfectly, but this is more than she can bear.  With a shriek she changes into her own form and flies up into the air, intending to make her escape.

This is exactly what Hanuman has been expecting.  In no time at all he is up in the air and in pursuit.  Poor Benyagai is no match for him in speed, and still less in strength.  Hanuman overtakes her, seizes her by her long and flowing tresses, and drags her unceremoniously back to the camp.
