The great evil
Leo would be the last to realise that his oldest son had become the source of all evil. When he finally saw the truth he would be angry at himself for not seeing it sooner. He would blame himself for what had happened, and he would swear to change it.
After Pipers death Wyatt would hunt down demons every day. It would take some time before Leo noticed; he would be busy with the elders, trying to make up for the lost charmed one. But he would realise, and he would try to talk with Wyatt. Try to get him to see the greater good in the world. Trying to convince him that his mom wouldn't want him to use his life seeking revenge for her. But Wyatt would just laugh at him, and orb out. Leo would orb after him and drag him back. He would yell at Wyatt, he would beg him, he would try to understand him, but Wyatt would just laugh. And Leo would be afraid that his son was loosing his mind. Leo would spend days that way, trying to get through to Wyatt. And suddenly someday Wyatt would say okay and promise to go to school the next day, and Leo would go back to the elders, thankful that Chris at least dealt with his sorrow without going demon hunting like Wyatt and Phoebe. And he would stop in his tracks, realising he actually had no idea of how Chris was coping; he hadn't talked with him for days. Leo was about to orb to Chris, but when he sensed for him he found him in the company of Wyatt, and he wouldn't want to disturb them. He would think that Wyatt probably could use his brother right now.
It would take three months before Leo realised that Wyatt had lied to him, that he was spending a lot of his time in the underworld. It would be by coincidence.
Leo would be in the underworld himself, looking for the new treat. The elders had tried scrying for a big evil power and they had found it to be somewhere in this part of the underworld and seven of them had orbed down there to try and locate it. But Leo wouldn't find the evil; he would find his son, killing two demons. He would go home with Wyatt demanding an explanation, and Wyatt would yell at him, saying that he at least did something to make the world a better place, instead of just sitting on a cloud meditating. And then Leo would do something he would regret the rest of his life. He would allow Wyatt to continue demon hunting. Sure, he would tell Wyatt he didn't like it, and he would tell Wyatt he couldn't go on forever, but for now, Leo would let him be, thinking that Wyatt needed to let of steam. He would convince himself that Wyatt in the end would see the light.
Leo would get in a fight with the other elders only a week after Phoebes death. The other elders had discovered Wyatt demon hunting, and they demanded that Leo put a stop to it. If he didn't they would. They would say it wasn't healthy, that it was destroying the balance, that it wasn't Wyatt's purpose in life to revenge. And Leo would loose his temper. He had lost almost all of his family. He had lost some of the most important people in his life, he was afraid he was loosing his youngest son too, loosing him because he had done his job as an elder, and now, the elders were accusing him of being a bad father, the elders with all their talk, but no action.
Of course he would know it was how it was supposed to be, the elders didn't act, they kept up the balance, but at that moment he felt like Piper and her sisters always had. He would feel that the elders tried to control his faith and his son's. They hadn't done anything to actually save Piper; on the contrary, they had kept him from her when she was dying by putting him on mute. Live was happening while the elders were talking, and now they dared to lecture him, the robed fools who had never known how it was to love and live, how it was to raise two children alone. He left the elders in rage, and wouldn't return to them until weeks after.
When he returned the other elders would try to get him to see the truth, trying to get him to take action, but Leo was stubborn, he knew what was best for his son. He would only admit to himself, when he was alone late at night, that maybe he couldn't do this alone, that the reason he let Wyatt vanquish all those demons was that he too wanted to revenge Piper, to kill and destroy everyone who had had something to do with her death.
Months after Victor's funeral Leo would orb into the house in the middle of the day. He would have orbed out in the middle of an elder meeting. Suddenly feeling an urge to se his sons. He would want to surprise them. They wouldn't hear him orb in, he would stand behind the door and hear his sons shouting.
"So that's it Wyatt, that is your excuse?"
"It's not an excuse little brother, it's the reason, she tried to stop me."
"Of course she did, you were going to kill her whitelighter!"
"He is a whitelighter, he is already dead"
"You were aiming at him with a darklighters arrow!"
"I wanted to see how it worked, but that stupid witch interrupted and made the arrow into water, cool power actually."
"So that's what you're doing now, testing darklighter arrows, who are you going to try it on next, me, or dad!"
"I was thinking the elders, there are way too many of them in this world and they are planning to bind my powers."
"Really? I wish them luck!"
"Don't bother, they are not going to succeed, I'm going to make sure of that."
"I'm going to stop you too Wyatt, somehow!"
"How, by telling dad?"
"Like he would believe me, he still thinks you're an angel, not even his precious elders can make see what you have become, killing whitelighters and witches and who knows what else."
"I'm just trying to create a better world Chris"
"Better, for whom?"
"Us, the magic community, a world where we don't have to live in hiding, where we don't have to do whatever those stupid elders tell us to, where we can actually use our powers and be the superiors we are meant to be!"
"You have lost your mind Wyatt; you don't have the right to rule just because you can!"
"Yes I do, join me Chris, help me rule, together we're the last of the Halliwels, and we can lay the world at over feet"
"Never, Wyatt, I'm not crazy."
Leo would stand rooted to the spot, not believing what he was hearing. After Chris' last word he would hear a crash and he would run into the room. He would see Wyatt stand in the middle of the room, and Chris laying on the floor, near the wall, broken pictures from the wall around him. Both of his sons would stare at him for a moment, no one would say anything. Then Wyatt would hold out his hand and the book of shadow would appear in his hand surrounded by black orbs. Then he would give Leo a cold smile, and turn to Chris.
"We'll talk again Chris."
And with those words he would orb out, his orbs black.
Chris would stand, take one look at Leo, and the he would orb out too, his orbs still perfectly white. And Leo would stand alone in the middle of the room, broken pictures on the floor. It would be exactly two years, three months and twenty two days since he had orbed into this room, finding his wife dead on the floor.
