So if you're curious how the episode could've ended:

To reach the happy ending you had to:
 * Choose to guard the glaf with Brick or shoot with Scott. Once Vito appears, he knocks CO out of the Rats' fort. She notices B's idea doesn't work the way it did anymore. Once she hears Scott accusing B of a sabotage, she does the math, and realizes he's the evil one here.
 * Choose to expose him, asking Dawn for help. In this case everyone finds out Scott the traitor and an antagonist. Even despite your friends would believe you, Scott could convince them you're trying to blame him for something you did. Choosing Dawn to comfirm your word helped them to believe in you, and also made the Maggots (who were also present during that scene) believe you as well, especially since the Maggots wouldn't believe you in other case (maybe minus Dakota and Zoey).
 * Convince Dakota to stay in the game after bribing Chris again to fire Sam in at the end of episode 6.
 * Happy ending ends with Scott being eliminated and Dakota staying after Sam's loss of his job in episode 6(in case she'll be still in the game).

To reach neutral ending you had to:
 * Choose to steal the Maggots' flag.
 * Choose not to help Staci after she was frozen.
 * There would be an option to either attack or avoid Jo (pushing Cameron away would be no problem). However, both options would actually be successul (you'll see why even attacking Jo would succeed in the trivia section). As a result, Rats would win thanks to you.
 * Conversation with Dakota would happen before the elimination ceremony. If you suggested her to quit once Sam wouldn't be an intern anymore, she'd tell her daddy to bribe Chris again in this episode, and leave the show with Sam to spend more time with him at Playa Des Losers.
 * If you suggested Dakota to try to win for Sam, a random Maggot that doesn't contribute to the main plot (Cameron) would be eliminated instead (in his case, it'd be because he failed at guarding the flag even more than Jo, who's also a great contribution for her team).
 * As a result, you wouldn't find out about Scott's true plan. He'd remain your enemy, but you wouldn't find out about his antagonism either. He also wouldn't try to frame B or anyone else.
 * As you can see there are pros and cons of this version, which is why it's neutral. I guess Dakota's elimination would decide whether it was more bad or good ending.

To reach bad ending you had to:
 * Choose to guard the flag with Brick or shoot with Scott.
 * Once CO found out about Scott's plan, choose to expose Scott, by only believing being nice to your friends was enough, or only asking Chris for the evidence from the cameras. In this case, Scott would frame you.
 * However, he wouldn't vote you off. He'd convince the others to vote for your friend, Dawn, to hurt you more, knowing that her powers make her a threat and that being disliked would make it harder for you to stay in the competition. It'd also strain your relationship with Brick and friendships with the other Rats, and also cause you to be disliked by the Maggots.

Choosing to do nothing after finding out Scott's plan would result in B's elimination, as in the real version. Personally, I'd call it a bad ending, but since it wouldn't be you, or one of your really close friends, I guess some of you could call it neutral. It'd be more of a bad ending anyway though, as if anyone found out you knew about this but remained silent in one of the future episodes (that is if RBW continued this plot), your relationships with the others would be strained, possibly causing you to be as disliked as in the bad ending.

Trivia:
 * No matter what CO couldn't be eliminated. That's the rule of episodes written by someone other than RBW. That is unless he'll change this rule in the future, so the third episodes would be even more unpredictable.
 * This is also why CO would succeed even if she attacked Jo, who's definitely stronger than her. If she lost to her and lost for her team, she'd go home, which couldn't happen.
 * Inability to eliminate CO is also the reason why Scott would target Dawn instead (with a good reason for it) in bad ending, or apparently randomly changed his mind in the good ending (not that his vote would change anything in this version).
 * Rats would win only in the neutral ending.
 * Counting all versions, 5 different contestants could be eliminated: Scott (good), Dakota (neutral, bad), Cameron (neutral, good), B (neutral, bad), and Dawn (bad).
 * However, if there was no rule that I couldn't eliminate CO, she'd be eliminated if you chose to attack Jo to steal the Maggots' flag and failed.
