No!" Aginor shouted. "You shall not have it! It is mine!"

Rand did not move, and neither did the Forsaken, yet they fought as surely as if they grappled in the dust. Sweat beaded on Aginor's face, no longer withered, no longer old, that of a strong man in his prime. Rand pulsed with the beating in the cord, like the heartbeat of the world. It filled his being. Light filled his mind, till only a corner was left for what was himself. He wrapped the void around that nook; sheltered in emptiness. Away!"Mine!" Aginor cried. "Mine!"

Warmth built in Rand, the warmth of the sun, the radiance of the sun, bursting, the awful radiance of light, of the Light. Away!

"Mine!" Flame shot from Aginor's mouth, broke through his eyes like spears of fire, and he screamed.

Rand and Aginor were fighting for control of the Well as surely as Asmodean and Rand fought over the CK.

Then let's not forget that he overcame Ishamael moments later with no angreal involved either...

Against the Shadow

As all broke apart around him, Rand pointed the sword at Ba'alzamon's heart. "It is ended!"

Light lanced from the blade, coruscating in a shower of fiery sparks like droplets of molten, white metal. Wailing, Ba'alzamon threw up his arms in a vain effort to shield himself. Flames shrieked in his eyes, joining with other flames as the stone ignited, the stone of the cracking walls, the stone of the pitching floor, the stone showering from the ceiling. Rand felt the bright thread attached to him thinning, till only the glow itself remained, but he strained harder, not knowing what he did, or how, only that this had to be ended. It has to be ended!

Fire filled the chamber, a solid flame. He could see Ba'alzamon withering like a leaf, hear him howling, feel the shrieks grating on his bones. The flame became pure, white light, brighter than the sun. Then the last flicker of the thread was gone, and he was falling through endless black and Ba'alzamon's fading howl.

or so you think Ishamael just stood there and did nothing while Rand attacked him?
