A/N: This is my very first story. Please, be nice.

It was such a simple mission. How had it gone so wrong?

Earlier that day

Artemis was the last one to arrive. M'gann was in the kitchen. Superboy was watching TV. Kaldur was reading a book. Wally and Robin were laughing at something on the laptop in fornt of them. It was another day at Mount Justice. Artemis settled in, and the day began.

M'gann looked up at the sudden shouting from the commons room. Wally and Artemsi were at it again. Robin had moved to another spot on the sofa to give them more room. Kaldur gave up on trying to read and joined Superboy in watching TV. Robin turned up the volume on his YouTube video. Artemis and Wally yelled a little louder. Superboy turned up the TV volume. The noise was gradually reaching a crescendo, so loud that M'gann couldn't hear herself think. There was just so much noise-

"OW!" M'gann hadn't realized that the knife she was using was getting closer to her hand until it cut her. She turned to the sink and grabbed a towel.

"Are you alright?" M'gann heard a familiar, gruff voice behind her. She turned around and found herself staring at her teammate's… chest…

"Oh-oh yeah! Uh," she stammered. Of course, of course Superboy would have heard her, with his super-hearing. "Yeah, the knife just… ah… slipped…" M'gann turned back to the sink. Some blood was starting to seep through the towel, dark green against white.

"It's… Green?" Superboy was looking at her hand, too.

"Oh, yes, part of being a Martian. Our blood is different. It's also the only thing about us we can't change. No matter what we shift into, it's always green…" M'gann trailed off, realizing she was babbling.

"Sorry," she rushed to apologize, "sorry, I just-"

She was cut off as a message came in from Batman.

They had a mission.

A/N: Yes, I know, it's short. Not really worth the T rating. But stay tuned for the next chapter, with better action.
