(Slight sidestep towards the end of Chapter 29)

Ruby, had somehow managed to get chased away from the fortifications. Even she knew where the hold-out position was located, kinda hard not to when the words in the air were curses, gunsmoke, dust and the occasional explosion along with high-flying Grimm.

Most reasonable people would run for the noise as it was the potential sound of salvation or destruction. Unfortunately for Ruby, she was a Branwen and a Rose; her elder brother had become her role-model and she naturally fell into the Trope of 'Big Damn Hero'. Although, people would say she was born to it. Her desire to help a friend had led her to the top the of Beacon Communication Tower.

As she made it to the top of the tower, she saw Pyrrha and Cinder clashing. It appeared Cinder was still going strong whilst Pyrrha had been flagging. Their clothing was torn and cut or battered and bashed, both of them were eying each other, trying to get someone to make the wrong move.

Just as Ruby landed with a three-point landing Cinder unleashed two arrows. Both veered sharply away from Pyrrah, as the Spartan warrior unleashed a discharge of polarity. Well the arrows moved away from her as planned, however one was flung immediately at Ruby and as for the other, it turned to glass-fragments before reforming into an arrow and appeared in Pyrrha's throat. Pyrrha stopped still, her hands reached for her throat and slowly fell forwards "It appears you simply weren't worthy." Cinder mocked as she ignited Pyrrha with an intense fire, turning her into a statue before dissolving her in a gold light.

Ruby managed to deflect and shatter the arrow that had came her way. Her eyes glazed over, she looked at Cinder; battered, burnt but ultimately smirking "Little Red, so upset…Your brother couldn't stop me. What makes you think that you can?"

Ruby's eyes hardened with rage "You'll pay Cinder. You'll pay for what you've done." Then everything went white. Cinder's eyes widening in horror as an arm went up in front of her to protect her face." The Dragon Grimm that she hadn't had time to get flustered over, turned to stone and her hearing went she heard the distinctive sound of stone shattering and someone grabbing her.

"Miss Xiao-Long, your arm…well we can heal it…Less heal more regrow it as the injury was not immediately cauterised." Drawled Snape, panic in his eyes as he stemmed the bleeding.

Yang looked at the Potions Master "How?"

"Use of these: Skelegrow, Musclgrowth and Blood Replenisher. All of them say exactly that on the bottle."

Yang eyed them even more so "What would my cousin say about them and you?"

Snape snorted "Mr. Potter would say that the potions will help, they'll be disgusting that they'll help. He and I…I'm not fond of him due to his legacy, but I don't hate him. However, due to certain mistakes in my youth have given me some unfortunate positions in life, and thus I must adorn many guises to protect my life, those I keep close to me and the School. Mr. Potter, Miss Xiao-Long is not one I intend to anger if I wish to survive. I will protect my School and its students with my life if I must. I do not expect or wish for you to trust me as a person, but trust me as a Teacher."

Yang nodded and gulped down the potions. Due to her aura being depleted, the potions quickly got to work. The Skelegrow felt like massive pins and needles; thankfully Snape had put a concealment charm around them preventing anyone from seeing. As a white flash lit up the night sky "Miss Xiao-Long, what has Mr. Potter…" Snape began as he inspected the bone-growth and repair.

"That wasn't Harry, Mister Snape. Harry's over there." Snape looked over his shoulder to see Harry slumped against the barrier.

"Then who?"

"Ruby, my sister…Really my cousin. But we were raised together…"

"And didn't know about Miss Rose's brother. Understandable…" Snape took a calming breath "…What is she like?"

Yang gulped down the other two potions "You know Harry, well take away the height, swap the gender, minus the cursing, add naivety and a genuine desire to help people."

Snape blanched "In other words a much politer, petite and female but still bull-headed…Merlin, save me. I advise you rest that arm for at least a month Miss. Xiao-Long."

With that Snape took off to tend to the rest of the wounded as Taiyang made his way over "Your okay! I thought you lost an arm!"

"Snape…He made me drink some disgusting potions, he called…Anyway new arm. Where's Ruby?"

"Right here Kiddo." It was Qrow, Qrow effortlessly scaled the barrier carrying Ruby, Crescent Rose and Harbinger with no sign of discomfort.

By now various students had made it to Atlesian Rescue Vessels taking them home. The upright members of Team NIKL looked at one another "Head to Shade Academy via Patch. That way we can give Neville instructions on where to meet us after he's finished everything."

"Team HAND will join you. When they come back, they're going to be chased by everyone. Damania commented fixing Adam and Nanuuk with a solid glare." The Bull and Polar-Bear both nodded in acquisition of their Team Leaders' official choice.

It was then Harry began to stir "Ow…That…sucked. We get the Dragon?"

"Yes and No. No we didn't get it, because it's…in pieces Harry." Said Charlie as he pulled Harry to his feet.

"It would have been cool to examine it but the fact it was leaking pustules of Grimm; figured it'd be too much of a hassle. I shudder to think what You-Know-Who would do if he found out about these things." Charlie went to say.

Harry paled "You know what Charlie, that is a very much Tommy thing to do. If you can't call him Voldemort, Charlie, call him Tom, Tommy or even Tom Marvolo Riddle; no matter what form he takes, he hates being addressed by that name."

The Order of the Phoenix's eyes widened, apparently this information had not been disclosed; particularly amongst the older members. Moody for one whose eyes widened. The one-eyed and one-legged auror, knew of the name because like Ron Weasley both saw Tom Riddle's name in the Trophy Room. Moody was known as an excellent academic much like the late James Potter and Sirius Black; but also had a bit of a joking side that had saddled him with a few detentions.

"Albus, you shoulda mentioned that. Now we've got a way to get around any sort of magic that Tom…might erect." Moody growled, before he turned to Neville and Harry.

"How are you two holding?"

Neville grunted as he pushed himself to his feet "Feel like a Goliath with a head injury."

"Feel like a stoned Wallboo. Kangaroo-type Grimm, whilst they can't be domesticated, they can get stoned. They like Opioid Berries."

Moody shook his head "In essence out of your head, but still too dumb to not know when to stop fightin'."

"In essence."

"Bit like punch-drunk grinning souls?"

Harry and Neville nodded at that, Harry clicked his fingers and a pair of backpacks, duffle-bags and two suitcases arrived at their feet. Velvet, looking rather battered and drained had staggered over to Harry. "You've gotta go?" She dejectedly, warm brown eyes looking up at him.

Harry nodded "Believe me, I don't wanna go. But…This…" Harry indicated around him "…the carnage, the chaos, the idiocy, You, the Brats and the Ozpin's Outraged Oddballing and Out-Of-Their-Minds Little Monsters…You're what I'm coming back to."

Velvet grinned at him, before wrapping her legs around his waist and kissing him on the mouth. "You'd better come back, don't be too much like you and don't lose your head."

Harry nodded "Yes ma'am. Not Eddard Stark, Ma'am."

"But your nobly stupid like him. Be more Tywin, less Eddard and more Tywin."

Harry nodded "So wear body armour to the bathroom…Can do."

"Harry, Neville…are the pair of you ready?" Dumbledore asked, his eyes not twinkling but looking rather down-trodden.

"As ready as we're ever going to be. Neville, if we survive this bullshit then yes. But, you hurt my sister…"

"Big brother torture me, I get it."

"No…just cover your head and count to 100 whilst using cheese wire to help with an opening of the wind-pipe."

Neville eyed Harry "You're a scary fuck sometimes Harry."

"Neville, I never knew you swung that way. I cannot in good consciousness reciprocate your affections, outside of comradery and brotherhood…OW!" Neville clipped Harry around the back of the head.

"Asshole. You know what I meant."

Dumbledore pulled out a Portkey "You, two wish to…"

"No Headmaster, just start the Trip back…This is hard enough as it is. You'll follow the contract."

"The lettering will be followed to the 't' and 'I'." Dumbledore replied "Although not necessarily the spirit or the contract at all as I mixed my names around. It applies to Albus Percival Brian Wulfric Dumbledore not Albus Percival Wulfric Brian."

(Patch)

Ruby woke to find Qrow in the chair next to her. "Dad?" Qrow woke with a start.

"Hey, kiddo…Nice to see you're alive…We've got a lot to talk about."

(Grimmauld Place)

Harry and Neville landed heavily with a thump "Now then my boys, let us discuss things." Dumbledore stated his eyes like icicles.

Harry felt his gut twist "You…don't intend to honour the contract."
