Remus John Lupin had not seen his wife in sixteen years.

He'd been terrified at the prospect of his child turning out as miserable as him, and out of some strange notion that leaving would fix everything, he'd left his wife.

About one year after he'd left his wife, he wasn't so shocked to find an owl perched on the window sill of the hotel room he'd been residing in. Attached to said owl's leg had been divorce papers. It pained Remus deeply to find the messy signature of his beloved wife- or ex-wife- Nymphadora Tonks already there. He'd signed it, feeling he owed at least that to Tonks. Leaving her four months pregnant with his child and not leaving as much as a note on the fridge, the least he could do is sign the damn papers. And so, Remus signed, and he hadn't heard from her since then. Nor had he ever even learned his child's name.

Now the werewolf was currently staring out the window of Hogwarts Express, headed to his newly re-achieved job as Defense Against the Dark Arts teacher. For once glad to see the moon, He was sharing his compartment with several young third years, two of which- much to his annoyance, and to the other children's- were now seemingly attempting to swallow each other. Imagine their surprise when they find out they were snogging in front of their teacher.

He breathed a sigh of relief when the train screeched to a stop, and the young wizards began to pile out. Remus couldn't resist the temptation to look around and see who he may recognize; he knew Harry's oldest son, James Sirius, wouldn't be attending Hogwarts for another two years. As for Remus's own child, he knew nothing of it. He was ashamed he had to call his only child an "it" since he'd never learned whether or not the child was a boy or girl. Harry had never told him, saying several times, rather angrily, "Find out for yourself".

Remus didn't know if his child would be here, he wasn't sure if he hoped it- oh there's that 'it' again- would be here, could he handle his child's hatred? Surely the child would hate him, after all, it would be sixteen by now. Most teenagers hate their father's without them ever walking out on their mother's.

"Ah, Remus!" He was suddenly pounded on the back, causing him to loose his footing and stagger forward.

"Hagrid, nice to see you again." Remus coughed, trying to steady his breath.

"C'mon, then, get ya' out of 'ere and inside, eh?" Remus nodded, gratefully, and followed behind Hagrid up to the school.

Once inside, everyone was quickly brought into the dining hall after their luggage had been dropped off into their rooms. The dinner was a blur of faces, some faces he knew or recognized; Neville Longbottom, the awkward, jittery boy had truly become a very impressive man. Hagrid had happily introduced him to several of the new Weasley children; Fred and Roxanne. Remus could barely process the fact that young Fred Weasley was now dead. The two children seemed ridiculously uncomfortable around him when they talked briefly to him, Roxanne being polite but looking around at everything in some hope of finding something to get her out of the situation. Fred just flat out didn't like him. Other Weasley's were attending the school, though they seemed conveniently missing at the moment.

Remus stood up and waved to the children as he was introduced by McGonagall, they clapped politely but some children whispered amongst themselves as they heard his name. No doubt they'd heard their stories about him. The werewolf who ran out on his pregnant wife and their baby. He was about to sit down when, one of the teachers who he didn't recognize, barked out at one of the students who was laughing- or arguing- with one of his friends.
"You there!" The boy turned, he looked disturbingly familiar. His hair was dark red and his eyes were bright blue, his laughing face fading into a confused one, the teacher nodded, "Yes, you! The young man next to Ms. Weasley and Mr. Longbottom." Ah, yes, Remus though, Another Weasley. It would make sense. But Remus nearly spit out the contents of his drink as the boy's features shifted, and suddenly the red headed boy's physique had drastically changed. His cropped bright red hair had grown out to his shoulders and, to Remus' shock, his hair color was now a vibrant blue. Remus examined his features, his lanky form, his unkept hair, and came to a realization,
"Me?" The boy called out,

"Yes! Mr. Tonks!" Remus had a coughing fit,

Tonks?
