The Black Knight scanned the space, looking at all the characters talking to each other after the awkwardness over seeing an older version of yourself had been broken. Over there he noticed Sephiran talking to a Bishop with his face obscured. He noticed another person wearing the same black armour, but without the helmet, clearly identifying the Black Knight as Begnion General Zelgius. And he also noticed that blue haired, red caped and green headbanded, little boy upstart, that had been in the forest on the night where he slew Greil (and survived because the King of Beasts was nearby), had fought him singlehandedly in Nados Castle (well, fine he had his sister with him, but the Black Knight also had a few troops to help out there), and had beaten him and caused that Castle to fall on him.
The Black Knight was not amused. Seeing his adversary here, he had to challenge this "Ike" again.
He stepped right in front of Ike's path. Drawing Alondite soundlessly from his scabbard, he aimed the point at his opponent's face.
"Hmph. I've been waiting for you, child."
Ike looked at the Black Knight in front of him, looked at Alondite's point at his face, before smacking Alondite away from his face by drawing Ragnell.
This time, the fight would be a different story than the close fought encounter in Nados Castle.
Ike swung Ragnell quickly before the Black Knight could assume a defensive pose with Alondite. Ike caught the Black Knight on the chest with the flat of the blade, knocking the wind out of the Black Knight. He followed up by slamming his armoured left shoulder into the same area, then swung Ragnell towards the Black Knight's helmet.
With an almighty "CLANG"!, the sound and the vibrations were too much for the Black Knight. He fell on his back on the ground, struggling to catch his breath and slowly slipping into unconsciousness from the blow.
The last thing the Black Knight heard was footsteps approaching, then his own voice above him congratulating the Ike on his victory.
"Impressive. Most impressive, Ike."
Author's Note: If you hadn't guessed what happened, the Path of Radiance Black Knight wanted to challenge Ike again, remembering the defeat at Nados Castle. The problem? He challenged the Radiant Dawn Ike instead. So RD Ike owned PoR Black Knight, and RD Black Knight (without the helmet, so it's Zelgius in Black armour, not his red) congratulates RD Ike.
I hope that's not too confusing.
