I don't normally do this, but I thought I would add a second alternative ending to this ficlet... (And yes, some lines have been used from Star Wars - kind of ironic really as Anakin turned Dark because of the loss of his mother and his worry about Padme, and Harry turned Dark because of Hermione using him and running away.)
Waiting in his throne room, the Dark Lord watched as two of the Agents dragged a stunned Hermione Granger from where she had been hiding out in a little village outside of Newcastle. Looking at her, he could see that she had been roughed up.
Leaving his throne, he knelt down beside her and looked at her face, her chocolate brown eyes bringing back memories of that night of passion.
Holding Hermione's hand, Harry looked up at the two Agents, casting a Cruciatus Curse. "I said bring her in, but I expressly ordered you not to harm a hair on her head," he said, annoyed with them. "Where's my son?"
"Dead my Lord. Granger wouldn't surrender him." The Agent that had been first to recover from the curse being cast at him. "Stebbins had to knock Granger out and then when the boy hit him, I reacted."
Harry stood up, towering over the Agent, fingering his wand. "Reacted? Reacted? I gave you express orders not to harm a hair on their heads and you reacted? I DON'T PAY YOU TO REACT! Avada Kedavra."
Both Agents fell down as the Dark Lord cast the spell at them. Waving his wand, he locked the doors of his throne room so nobody could enter. Turning to Hermione, he cast a number of spells intent on healing her when he suddenly stopped.
'Why am I healing the bitch. I wasted the last eleven years looking for her and my son and she does this. She doesn't deserve healing.'
Heading back to his throne, he pressed the button to summon one of his Agents. Keeping his wand in his hand, he watched as Luna Lovegood apparated in front of him.
"My Lord?"
Harry walked up towards her and, out of the blue, hit her. "You failed me Lovegood. You told me that Greengrass would stop Stebbins and Hopkins from harming my son. Instead, they killed James."
"Harry-"
"Don't Harry me Lovegood, you're just like the rest of them." He said as he took his wand out. "I've forgiven you many times for your failures, but this. This is the last time. Avada Kedavra."
Luna fell to the floor like a puppet having its strings cut, her lifeless body falling next to the bodies of two of his other Agents. At the same time, the doors to the Throne Room opened, Daphne Greengrass entering.
Before the former Slytherin could say anything, she was hit with the Cruciatus Curse.
"HARRY. STOP."
Harry turned to see Hermione sitting up, the injuries she had sustained at the hands of his two Agents. At the same time, he saw in the corner of his eye how he still had Greengrass under the Cruciatus.
"HARRY. STOP IT." Hermione shouted, struggling to get onto her feet.
"YOU DID THIS TO ME." Harry shouted back to her, watching as Daphne fell to the floor, convulsing.
"YOU WERE THE CHOSEN ONE" Hermione replied, "You were the one who defeated Voldemort. You were the one who brought the Wizarding World hope during the time of Voldemort's takeover and now this? You have become the very thing you swore to destroy."
"Don't lecture me, Granger." Harry retorted, heading to the door of the Throne Room. "You used me, and then you discarded me as you did with Krum and Weasley. I should have seen it before, but I was blinded by the love I had for you. You hid my son away from me and yet you claim you have the high ground."
"I-"
"Silencio"
Circling around the sitting form of Hermione, Harry raised his wand and, aiming at Hermione, cast the killing curse at her.
As her body hit the floor, the Wizarding World would never be the same again.
