Almost too quickly for me to follow, Jace ducked under Tyler's swipe and came up with his own claws extended, slashing across Tyler's belly.
He connected, but Tyler lurched back quickly enough to confine the damage to his shirt.
Jace twisted into another attack, more quickly than I'd expected given his bulk, going for Tyler's shoulder with his left hand. That drew blood; droplets spattered from Tyler's shoulder, and I heard the faint scrape of claws against bone. Tyler growled in pain and staggered back.
Jace's claws stuck for a split second, though, and that was enough: Tyler lashed out, raking his claws down Jace's extended arm.
Crimson blood soaked through Jace's white t-shirt, spreading like ink. Jace took a step back and shook his head as if to clear it.
When he threw himself back into the fight, his movements were slower. Noticeably slower.
And he was still bleeding — he wasn't healing.
And Parker was grinning, his eyes fixed on Jace's blood.
