Luke sighed out his breath as Caedus rejected his offer. He had wanted to try, anyway. Pulling deep on the resources of the Force, and breathing it in, he closed his eyes as Caedus flung the lightning at him. For a moment it surrounded him in such light and sound he was lost in the world of it, but then it reacted to what he was doing and was sucked into his body, into the Force within, and Luke's eyes opened, glowing as he let himself fill with the Force until his individuality was almost gone and only love and acceptance showed in him .
"I will always believe in Jacen Solo." And then the lightning flared out again, arcing to Caedus, but now green and looking like nothing more than a ball of lighting all filled with explosions.
And that lightning that was no longer lightning carried love, hope, acceptance, and the pure and unadulterated power of the Light Side, channeled through a willing man, one who loved his nephew, and was unwilling to let him slide gently into the night. All of that suddenly, was what was flung into Caedus.
