"Harry Potter must take more food! Dobby insists, there is plenty!"
The elf thrust all sorts of sweets -- cakes, cookies, and the like -- into Harry's hands. Peckish in the middle of the night, Harry had donned his invisibility cloak and snuck off to the kitchen where the elves, particularly Dobby, would be more than happy to load him up with treats. Dobby, in light of Harry's lack of a free arm, threw the cloak over the boy and bade him goodbye.
"Goodbye, Harry Potter! Next time, Dobby will gladly bring the food to him if Harry Potter so wishes!"
With a Seeker's adroitness, Harry balanced his stash of snacks as he made his way to Gryffindor Tower. He was close to his destination when, out of nowhere, Peeves came shooting down the hall. Invisible, Harry was forced to quickly sidestep to avoid a collision. Doing so caused him to trip on his baggy pajama bottoms, sending himself and his various food items to the floor. Harry, trying to salvage what was still edible, was rather surprised when a strong tug on the back of his neck almost brought him to his feet.
"Out of bed, Potter?"
Draco Malfoy, his skin looking paler than usual in contrast to the black bathrobe he wore, released his grip as Harry struggled to free himself and face his attacker. Time seemed to freeze as the two boys stared each other down. Suddenly, each went for his wand, Malfoy's in the pocket of his robe and Harry's in the elastic waistband of his pajama bottoms.
"Petrificus Totalus!" cried Malfoy, but Harry, knowing it was in Draco's nature to attack rather than defend, uttered Protego just in time to shield himself from a Full-Body Bind. He took Malfoy's momentary unsteadiness from the force of his spell's rebound to attempt to Disarm him, but overshot his target.
With wands slashing and twirling, the two young wizards tried their best to disable one another. Malfoy seemed to falter in his skill and determination as Harry gained ground by forcing him backward. When Harry drove Draco into an empty classroom, he knew he had him cornered and vulnerable.
A small smirk appeared on Malfoy's face as he swished his wand and shouted "Colloportus!" Harry, expecting an attack, had produced another Shield Charm but instead the door behind him squelched shut. Confused by this non-offensive spell, Harry barely heard Draco say "Incarcerous!" As ropes flew around Harry's wrists and ankles, Malfoy pointed his wand again at the door, muttering "Muffliato" and preventing anyone from hearing what went on inside the locked classroom.
Harry glanced at the floor where his wand lay, having dropped it when he was swooped up by ropes that now, being magically taut, suspended him halfway between the floor and ceiling. As Draco approached him, wand in hand, Harry realized the sheer hopelessness of the situation.
