A/N: This is a Parasitica-based fic I wrote before the episode aired...it's collecting cyber dust on my hard drive, so why not? It's the result of me being excited to see Mikey fight his bros (which he will do in two weeks!) and the need to see a Mikey/Raph pair up in the show.

Disclaimer: Is this what happened in the ep? No, so I must not own it.

Raph rubbed at his arm where the stupid wasp stung him. Despite Don's immediate first aid attention to the sting, it was tingling.

It was worth it, though, as long as Mikey didn't have to suffer this.

His baby brother…

The one he'd do anything to protect.

The red-banded turtle tried to focus on the building across the street, but the tingling sensation just became worse and spread throughout his arm. Eventually, it has spread all the way to his fingertips and started to his chest.

"You okay, bro?" Mikey was looking at Raph with large, blue eyes filled with concern. "You don't look too good…"

"I'm fine." Right as he said that, the tingling reached his head and started going down his other arm and legs. Once his entire head was encased in the tingling sensation, a thought that wasn't his own entered his mind and scared him.

'Attack the child.'

Mikey. The child of the group.

No. Anyone but him.

'I'm not going to hurt Mikey.'

The tingling finally encased his entire body, and he found his hands reaching for his sai.

"Raph, what are you doing? We're not supposed to engage unless absolutely necessary!"

'Destroy him.'

'He's my baby brother.'

"Mikey, I…I need you to run as far as you can from me." His hands were now wrapped around the sai and cramping from being unable to pull them out. "You're in danger by being near me…"

"Raphie, how an I in danger?" He gave his brother a look of pure innocence. "I'm always safe with you."

'Well, I'm feeling guilty here…'

"Please, just leave…" instead of leaving, the smaller turtle wrapped his arms around his brother and nuzzled into his neck.

"You're my protector…Nothing can happen to me when you're around…"

'That's what you think.'

Suddenly, Raph's arm shot out with the sai in hand, creating a deep cut on Mikey's bicep.

Green met blue as Mikey's eyes filled with almost to many emotions to pick out: surprise, fear, disappointment…

…and trust.

Despite being attacked by him, Mikey still trusted Raph.

He would never forgive himself if he caused those eyes to lose their light.

A/N: ...Yeah.
