Logan cocked an eyebrow when James made an unusual but fairly apt description of his self-appointed nemesis. He thought about Warpath's question for a moment. "Honestly? Dunno what it'll take, but I intend ta find out," he said, eyes narrowed thinking about it. "B'sides. Metal claws should do th'trick nicely, knocked down or not," he offered with a tiny grim smirk of malice that could have given nightmares to any civvies around who might have seen it. Yes, Logan did have revenge on his mind. Serena had been made to suffer an atrocious death that she did not deserve. It was the kind of death Logan himself felt men like him had earned. No one else should have to suffer it, especially not someone as kind and good as Serena had been. It wasn't fair. It was unacceptable. Sabretooth had to learn that this kind of action wouldn't fly. It was one thing when he was toying with Logan himself. He hadn't forgotten how he'd lost an eye and a leg to that bastard before his healing factor came online and gave them back to him. But it was another when he started going after the people Logan cared about. Creed had crossed the line, and Logan had a good mind to show him just how badly.
He nodded, his mouth tightening as James brought him back to the task at hand, which was locating and retrieving Karr. It certainly didn't matter to Logan whether Karr wanted to come back or not. He wasn't going to let his boy stick his neck out and have Creed lop his fool head off for being stubborn. Karr was coming home one way or another, no matter how much he might hate Logan for it. That's what dads were for anyway; the hairy man figured; to protect, lay down the law, and be hated for it. The way Logan saw it, he didn't give a rat's ass if Karr hated him, so long as he was alive to do it.
He did groan audibly at James' last question. "When it comes to that kid, yer guess is as good as mine. Lil' stubborn sonumbitch," he grumbled the last, so only James could hear it.
