Nothing in his Life Became him like Leaving it

This plot involves my FrostClan apprentice Mosspaw!
This plot will go on for a while, and it's very open and subject to change through RPing.
I don't know what the outcome will be, and there are several different things that can happen.
More info is after the plot, such as characters and expected threads.
So without further ado, let's get to the plot!

Moss is a very bitter cat who doesn't feel like he fits in with his clan. During his apprenticeship, he will meet this other apprentice (gender doesn't matter) in the clan, and while Moss will resist making friends at first, the other cat (let's call them CatA just for consistency) will continue to pursue friendship. Eventually Moss will get worn down, and the two of them will become super close friends. They become best friends, hanging out all the time, they're inseparable, etc. etc.
Eventually, the two become warriors together. One day they go to a gathering, and Moss meets this cat (again gender doesn't matter, let's call them CatB) around the same age from a different clan (preferably one that borders Frost). The two hit it off instantly, which is surprising considering Moss's nature (CatA's reaction to this is entirely up to the RPer). Unknown to CatA, Moss and CatB start meeting up in secret. It's not necessarily anything malicious or bad or even romantic (though it can grow into that wink wonk), just two friends meeting up. Because of their frequent meetings, the two of them grow to become very close friends, even rivaling his and CatA's friendship, despite knowing each other for a much shorter amount of time.
One day, CatA finds Moss sneaking out of the camp, and sees him and CatB interact, and sees how close they've become. The RPer can decide whether they want CatA to approach Moss about right then and there, back at camp, the next day, etc (though I do think CatA would talk to Moss about it, given their close friendship). It's also up to the RPer whether CatA will get mad, concerned, sad, whatever. Regardless, Moss will get bitter and peeved by it, and probably start a fight. The fight will get out of hand, and end with the two of them splitting ways. It's up to the RPer how CatA will feel about this.
Angry, Moss will meet with CatB one day and complain about CatA. He'll mention that he wishes he could just leave FrostClan, and will then get the idea of joining CatB's clan. He'll tell them this idea excitedly, and it's up to the RPer as to how they respond.
A while passes, and during this time Moss and CatA don't talk much. It's up to the RPer how CatA feels, and whether they have been trying to talk to Moss. Either way, Moss makes up his mind. He gets up in the middle of the night, and gets ready to meet CatB so they can go to their clan together. CatA finds Moss before he can reach CatB, and asks him what he's doing. Moss explains, and from there it's entirely open.
Will CatA try to convince Moss to stay?
Will they let him go?
What will Moss decide to do?
Stay tuned to find out.

Taken by: ouisense
Things to keep in mind:

Threads
- preferably at least two threads between Moss and CatA before CatB gets introduced
(can both be as apprentices or one as apprentice, one as young warriors)
- first thread between Moss and CatB will be at gathering
- should have one thread after that with just the two of them
- after that we'll have a thread between Moss and CatB where CatA sees them
- can have more threads in between, but not necessary
- finally, the thread that decides it all
