What are brothers for? [TSAMS based, plus a mix!]

#1: Infection

{Disclaimer: I don't own these characters, or the photos, I created this au based off of a "Last of Us" AU animation I saw.}

  (Sun POV)

"Monty said he would be back soon...I have faith that he will." Earth said, she fiddled with her hair, she was obviously distressed. "How long has it been?" Moon asked, I sighed and crossed my arms. "At least two days..." I said, feeling a sudden chill. A cold, haunting feeling...I glanced around the daycare a bit, before...

"VIRUS DETECTED. SHUTTING DOWN SUPER-MEGA PIZZA-PLEX. ALL ROBOTIC STAFF AT RISK. CLOSING DAYCARE." The computer said over the speakers. I felt my heart sink. Earth looked terrified, she ran for the daycare entrance, but Moon grabbed her arm. "MONTY!" She cried, I felt horrible, "Wait...Look..." Moon whispered, we all glanced over to see a cleaner bot, it had made it inside the daycare before the doors had shut.

But something was wrong with it. It made a loud whirring sound, It was leaking oil from its eyes, its audio receptors, all over basically. The poor thing looked so sickly, it slowly crept up to us, leaving a trail as it went. 

I heard a gasp, which caught my attention, I glance over to Lunar. "Oh...the poor bot..." He whispered. "It just needs some help." He said, walking up to it. "LUNAR I KNOW WHAT THE VIRUS DOES! AND HOW IT TRAVELS! DON'T TOUCH THAT!" We heard Solar yell, he ran as fast as he could over to us, but it was too late, Lunar had touched the poor cleaner bot. 

I put my hands together, building up a little ball of star energy, and created a barrier around the bot and Lunar, "Smart." Moon said, as he pulled Earth close for a hug, she sobbed in his arms, it took a while to catch my breath. I hate how tired star energy makes me...

"What does this virus do?" Lunar asked, getting scared. I glanced up at Solar, who was holding back tears. obviously worried for Lunar. "Well-" His voice cracked, then he cleared his throat. "It's long term...that's why I made copies of our data and hard-drives, so no-one will be losing memories again..." He glanced at Moon, they exchanged glances and nodded. 

"What does it do?" Moon asked. Solar sighed, "It travels through physical contact, but it takes five days to actually feel the effects of the virus...after ten days, the virus is making it's way through the system, you'll hallucinate, see things...after fifteen you'll leak oil, like this cleaner bot...but since it has no sentience, at the twenty day mark, it will have a system failure and shut down...but if any of us get infected..." He paused, glancing at Lunar.

"We'll become homicide codes..." He whispered. Tears streaming down his face, I felt so, so bad...but I wasn't sure what to say...everything happened so fast...
