Summary
You always went lookin' for an easy way out
Leave the pain you can't solve with the folks you let down
Like the world just restarts, like the clock just resets
Like we all just move on, like we all just forget
And you tell yourself lies and disguise them as facts
It’ll hurt half as much if you drive twice as fastOr
The apocalypse is here and Stacy Marsh is most likely what stands between the remaining survivors of South Park and death

Summary
Based on Chrissy Chlapecka's Christine
Grace has been having a ghost in his dreams surrounded by an ocean of blood. The ghost's anger burdens him. He feels like he has known this ghost for so long as he speaks to him through song. Sometimes, he can feel him slipping through his fingers but hears him every night cycle.
Grace didn't think too much on his continuous nightmares on their way back to Erid. That is until he and Rocky get a series of transmissions from an unknown origin. The transmissions are from another human calling out.
Driven by Rocky's encouragement, Grace makes the decision to respond and lend what ever aid the two could provide. Even if his nightmares continue to haunt him, even when he is awake, becoming worse as they get closer to the mysterious red moon he has made the decision to save the owner of the mysterious voice.

Summary
“Which one are you?”
“…Ryland.”
Tom looked him over carefully.
Beat.
Then, the only word that left Ryder’s mouth was, “Wow.”
“What does wow mean?” Ryland narrowed his eyes.
Tom tilted his head slightly. “I really expected another Colt.”
“…what?”
Tom gestured vaguely at Ryland as a whole.
The glasses.
The oversized dark hoodie despite the heat.
The careful posture.
The iced coffee held like emotional support equipment.
“I don’t know,” Tom admitted. “More sunglasses, buff, badass, maybe.”
“I don’t see what’s so different about me.” Ryland frowned.
Tom glanced between the twins again, visibly trying to put it into words. “You’re just…” He gestured vaguely at Ryland. “Less likely to survive a car chase.”
Ryland stared at him. “That is not a personality trait.”
“It kind of is.”
“I could survive a car chase.”
Tom looked deeply unconvinced. “Could you?”Bookmarked by RiverRaenn

Summary
"Never judge a book by it's cover king," He waggled a finger at Colt.
"But you just—" Colt gaped his mouth in disbelief. "You can not hit on my brother."
"Oh I believe I just did," Ryder sneered at him proudly, feeling as though he already won the battle.
Or
Tom Ryder starts flirting with Colt's brother to annoy him. Ryland is absolutely oblivious.

Summary
“So? What's so interesting that’s keeping your attention from your amazing, super-cool, and even hotter boyfriend?” Tom asks, leaning into Ryland’s space to look at the tablet resting on his lap.
“It's Dr. Scythers’s latest publication.”
Or; Tom finds out about the guy who ruined his boyfriend’s career. Safe to say he’s not happy. It's a good thing he’s rich and powerful, though.

Summary
“Nice work today, fall guy!”
As he passed, Tom leant down and smacked the guy's ass hard enough to make him stumble, grinning to himself at his own endless skill to get on Colt’s nerves. He ducked around Colt and made to keep on walking, expecting the typical grumble and snarky comment from behind him.
Except there wasn’t a grumble, though - instead, Colt Seavers fucking squeaked.
Or - Tom Ryder doesn't know Colt has a twin.
