Okay, first off.
Didn't you dethrone Cassie?
Things really snowballed from this, so I'd like to make some clarifications.
Gonna have to agree with Ny here.
I don't think a little battle would've caused...this.
but it did make her do challenge the Sinnoh league, I think.
This is the correct outcome of Cassie's loss to Damian. Although we had discuss things privately, there seems to have been some misinterpretation of the information I was relaying you, Mega, and you seem to have jumped to conclusions from it.
"Now, however, Cassie has become very downtrodden and quiet. She'd lost that pride, that air of confidence, self assurance, drive, and purpose, and in its place is just... Hollowness and utter exhaustion. The detachment in her eyes have only increased tenfold, and instead of that thinking look, she's more prone to just spacing out. Overtaken by a certain darkness. She holds her head low, slinks about instead of striding, and hardly ever has any expressions on her face. She separates herself from groups to be by her lonesome, and is a lot more blunt than she used to be. Sometimes, she'd even utter complete nonsense. Like someone on the verge of insanity." Direct quote from her, I didn't mean that single battle caused all of it, just that it may have been a snowball effect as she was a much different person entering the battle and before that I can post the beforehand description pen gave of her aswell
If you remember this paragraph's predecessor, I had described that Cassie took the loss quite well. It did not break her spirit or wipe her pride away and she had taken great pleasure from the battle despite her loss. It opened her eyes that she was still weak, and spurred her on to her quest for strength in Sinnoh instead.
Back then, Cassie is this person with an iron will who always holds her head up high even in the face of defeat. She's prideful, but she's a good sport, and would've congratulated Damian on his win against her with a satisfied laugh from the thrill he'd given her, and then tell him, "I guess this means you'll have go on to win it all in my place then." And kiss him on either side of his cheeks, which is a French custom called faire la bise, as a farewell at him before taking her leave.
That being said, Burble is correct when he mentioned Cassie never actually challenging the Unova League. I suppose I should've clarified this to you Mega, but their battle would've taken place before Damian was champion, perhaps a selection round, and he and Cassie were simply two hopefuls for the title. He would've knocked her out, in such a condition. Hence why she told him he needed to win in her place.
The traits that you quoted, Mega, was after all the shit she went through, it didn't accumulate from her loss to Damian. In fact, if anything Damian would have served as her inspiration to get stronger and would have gotten stronger already from this experience, and not the other way around.
my first post is up, hopefully its up to standard! I wish I had been able to do it without being exhausted but alas I wanted to give it a go anyway.
Now that that's cleared up, let's talk about your post Jake.
Within normal circumstances your post would have been easily acceptable in our standards. Unfortunately that is not the case. However I would first like to commend you on your spectacular highlight of Knox's special quirk; his ability to classify the stone make up of the cave and identify the assets it may hold from there. I also found your idea of using Bastille as a door very inspired! Surely his snoring would've scared away whatever wild pokemon had come by, and your detailing of his magnificence is greatly appreciated. Also, I knew I had gotten a fun character from you when you specified Knox's smart mouth, and I'm very satisfied on how it was showcased. His innocent little comment of "Room service?" really cracked me up! Oh, Cassie would just have a blast with him.
Now positives aside, with the length of your post being approximately only a quarter of what Curvy dished out, I would have expected it to be utter perfection. And frankly, it's not. I'm seeing a lot of spelling errors, mistypes, as well missing punctuation. There are also occasional capitalization errors that make your post look downright sloppy, and one thing I'm sorely missing is the lack of description on Knox's activities prior to being gassed. That explanation of why he hadn't encountered anyone else in the tournament.
You could go by Gerald's staying in his room the entire time, or perhaps Knox had simply decided to do a little excavation project away from the resort. Whatever it may be, I implore you to reread your post fix the errors I have mentioned.
At the moment, however, I'm not really arguing with anything major in your post. The ideas are all very original and reasonable, if not a bit crudely written. Perhaps simply rushed. I'm not even cracking down the whip on you for anything other than technicalities to further polish your post. I'm just your friendly neighborhood proofreader.
I can't believe Pen was nothing more than an item on your bucket list!
