Sure! But not much was ever written.
The fic was mainly John's attempts at getting closer to Lloyd (and reasons for them to resent each other). It was meant to be an exploration of John + Lloyd's relationship, since for it to be so terrible, I feel there must have been something beyond just the magic draining incident. My fic took place a few months before the magic draining.
I don't think those two were ever particularly close, but pre magic draining I don't think they were very antagonistic towards each other either. Pre magic draining, I see it as a mostly awkward + distant relationship where they struggle to find any common ground. All attempts at bonding are one-sided and usually doesn't go well. Not terribly, but like. they really have a hard time getting along since they're just so different.
There's also some hidden mutual resentment, but since this is before the magic draining, it was nothing too serious. (John was annoyed that Lloyd seemed ungrateful for all their mother's attempts at making him happy + wish he wasn't so difficult to deal with. Lloyd was jealous that everyone favored John)
John tried his very best to get along with him! Often inviting him to play together or go to the forest together etc. He always gets rejected though. But then Lloyd takes an interest in reading, and since John likes telling stories, John changes his approach by telling Lloyd stories instead. Most of it were highly exaggerated versions of whatever he did/saw in the forest that day. Lloyd listens because John somehow manages to make it sound interesting.
In one of the 'cute' scenes, John tries to talk to Lloyd like usual, only to be told to shut up. He prepares to leave Lloyd alone but before he walks out Lloyd says "I didn't tell you to leave." John stays and the two of them silently read books together.
I think I've already mentioned it before, but John also tries writing stories down for Lloyd to read. There's mistakes in them, which Lloyd likes to point out because he likes being better than John at something. The stories were pretty interesting though so Lloyd continued reading them despite the mistakes. But the truth is that many of those mistakes were purposefully added in since John noticed that Lloyd liked pointing them out.
They slowly start getting along better, but Lloyd overhears brystal saying something along the lines of wishing Lloyd was more like John. Because of this, he gets jealous, and purposefully does something to upset john. (I haven't figured out what, maybe rip up something he wrote?) They have a fight which leads to this:
“Mother loves you more!” Lloyd shouts, tears forming in his eyes.
“Of course she does!” John shouts back. “You're hard to love.”
As soon as the words leave his mouth, John’s eyes widen, and he takes a step back, shocked by his own statement. He attempts to put a hand on Lloyd’s shoulder. “Wait, Lloyd, I'm so sorry. I didn't mean it, I-”
Lloyd slaps his hand away.
“Get. Out.” Lloyd hisses, seething with rage.
John looks at Lloyd pleadingly. “I'm sorry, Lloyd, please, I didn't mean it-”
“GET OUT!” Lloyd screams. He grabs his wand and points it at John.
“Lloyd-”
Lloyd shoots.
And yay! Lloyd gets his first taste of committing violence, woohoo! John tries to apologise and make up for it, but Lloyd does not let go of grudges and never forgives him. This is also kinda what prompts him into seeing himself as more like a villain + fantasizing a world where John does not exist and he gets whatever he wants. idk.
