He grabbed Aloha by the neck.
"GAH- H-HEY—" Aloha instinctively grabbed Rider's wrist.
Rider didn't even know why he was doing this anymore. His heart was pounding out of his chest, feeling like he just drank five cups of coffee in one sitting. His mind was screaming at him to kill Aloha, kill them all, kill everybody.
He squeezed onto Aloha's neck, grabbing one of his arms with his other hand.
"GH-" Aloha's face turned red as he started to sweat. He should have expected this reaction. 
"I- DIDN—T- K-KI—-"
"HE'S NOT DEAD!!!" Rider screamed, sobbing. "DON'T EVEN SAY YOU DIDN'T KILL HIM, BECAUSE HE'S NOT DEAD!!!! BESIDES, WHO ELSE WOULD HAVE HURT HIM??!!?!" He twisted Aloha's arm.
"CH-CHIL—-" Aloha shrieked.
Rider held his arm still in its twisted position. "If I let go of you, you WILL help me fix him. I WILL KILL YOU. DO YOU UNDERSTAND?!"
"Y-YEAH—" Aloha nodded the best he could.
Rider scowled and let go of Aloha's arm and neck, holding his hurt wrist with his other hand. He didn't realize he was hurting himself in his own anger.
He went over into the bushes and kneeled down next to Goggles, checking for a pulse. It was a bit faint, but there. 
Aloha gasped and caught his breath. "C'MON DUDE- YOU GOTTA STOP WITH THE GRABBING—"
"YOU'VE GOTTA STOP EXPRESSING YOUR GODDAMN PERSONALITY SO MUCH BEFORE I BEAT YOU TO DEATH." Rider quickly checked to see where Goggles was injured. Someone got to his stomach. It looked practically as bad as when it was first slit.
Aloha peeked over Rider's shoulder. "Oh carp-"
"AAAGH—" Rider tried not to panic.
He looked at Aloha. "Hey, dipshit, go back to the roof and get the bandages, would ya?"
"Eh? Aight!" Aloha shrugged and made his way back to the Plaza.
Rider pressed Goggles's shirt against the wound and waited patiently. He was basically bullying Aloha and expecting him to help.
'I'm going to end this disease! I'll make sure that you can enjoy yourself again!'
Rider narrowed his eyes. 'What did Goggles try to do?' he wondered. 
Aloha seemed to be taking his time, although it had only been a couple of minutes. Every second counted. Rider could practically hear a clock ticking in his mind as he waited. 
"Tch." Rider slowly picked Goggles up, looking around. 'Where is he?'
".....Ou—"
Rider looked at Goggles. "H...uh...?"
"Hnnn—- R-Rid...er....?" Goggles opened his eyes a little bit, some blood dripping out of his mouth.
"GOGGLES...!!!" Rider blinked in surprise. "Can you breath?! How many fingers am I holding up??" He held up three fingers in front of Goggles.
"I'm-... sor—"
"Woah! Nows not the time to be makin' out with 'em." Aloha teased, walking into the small hiding space. "Heh, well, maybe nows the perfect time~"
"MAKING O- ALOHA, SHUT UP..!!! GIVE ME THE BANDAGES..!!"
"Aight! Maybe later~" Aloha winked at Goggles, tossing the roll of bandages to Rider.
"No, not ever." Rider caught them and set Goggles down, pulling up his shirt to see the wound on his stomach. 
Rider quickly started wrapping it up as carefully as possible.
"Aw... c'mon, you know you want to!" Aloha put his hands behind his head.
"Nope. I'm ignoring you now."
Blood seeped through every new layer of bandages Rider put on, so he continued to wrap and wrap.
Goggles slowly stopped his small twitching.
"Oh?" Aloha made a surprised expression.
Rider checked his pulse, pressing down on his stomach to help prevent blood loss.
Goggles didn't give much if at all any reaction.
Aloha's eyes widened, mouth gaping a bit.
Rider pressed his fingers a bit deeper into Goggles's neck, to feel for anything. He stopped everything he was doing to check, heart racing. He could feel something.
Rider quickly finished wrapping up his stomach. He pressed against it again, and found no blood was visible from the bandage.
He tucked in the end and tried to get Goggles to sit up.
