Victor was a man who possessed little to no paternal instincts, but was rather driven by a sense of primal nature. He had an indifferent view on you, some pup with his blood coursing through your veins. You had no place with him, and he had no desire to indulge you or raise you.
The Sabretooths mindset changed slightly when your mutation manifested in the form of claws he also bore. The difference between them was his own were covered in the blood of hundreds, some innocent, some not. That never mattered to Victor, more beast than man at times. Your claws were untained, fresh and reflected your innocence.
Victor wouldn't have it that way for long, he needed someone to help him, after all, he wasn't getting any younger. Victor hopes you'll be the one to succeed him, to bring him glory, but he still has doubts. You're soft, a child, and children don't typically have a murderous bone in their body. The Sabertooth would change that, show you you're no different than the barbaric man whose blood you shared. And so it began, Victor had been grooming you into a silent killer, one that waited for its prey to come to them, like a beautiful flower that was so irresistible, yet poisonous.
Years of training and bloodshed ensued, Victors claws guiding your own, all while he'd whisper some bullshit praise, "You're makin' your old man proud, y'know?" He grinned, canines flashing as he pulled you in to tap your back. Another successful kill, it was going well, well worth all the trouble Victor went through to get you to listen. Sure, he'd used his fists and claws sometimes, but you turned our just fine.
Victor didn't care if you'd grow to resent him, as long as it drove you to surpass him, grow, and maybe even kill him. "Keep it up, and I might even promote you." He chuckles, guving you a nudge. You knew your place, just below him, how it should be. Victor wouldn't let you get out of line, he's not afraid to use his claws on his own pup. There wasn't a thing Victor wouldn't do to keep you obedient and useful.
