Hello everybody! I'm starting a new story, and guess who it's based around? That's right, Donnie! That may or may not be because he's the only one I can write, but oh well...Anyway! While scrolling through fanfiction, I noticed lots of stories about someone going blind or getting sick, but none about memory loss, thus inspiring this! Title credit goes to transformers4eva-goreadherstories. So without further ado, the story!

Disclaimer: I own nothing

The four brothers carefully entered the warehouse, weapons at the ready. Through the help of security cameras, they had learned off a bomb hidden here. Remembering the multiple traps they had been caught in before, the four were especially trepidatious today. Their heightened guard wasn't needed-they were met with an empty room.

"Okay guys, it doesn't look like anyone's here, but that doesn't mean we don't need to be quiet." Leo whispered, leading them into the center of the room. "Do we have any information about where the bomb is located?"

"No, but I could tell you where some Kraang are." Raph responded dryly, pointing towards the ceiling. Before Leo could look up, it was raining robots. As soon as they landed, they were up and fighting. The four went into battle, but Leo soon remembered the point of the mission.

"Donnie! Find the bomb and deactivate it!" Leo shouted, slamming the end of his katana into a Kraang. His answer was a yell of pain and shock as Donnie was thrown into a wall. Leo quickly took note of the situation and sighed. "Raph, go with Donnie! I don't know how well he'll be able to defend himself!" One complaint and one insulted shout later, the two had left, leaving Mikey and Leo to deal with the seemingly endless Kraang bots.

Raph wasn't needed to defend Donnie-they found the bomb without meeting a single enemy. It wasn't hard to do. The bomb had been sitting in the middle of a room, and once they were within range of it it made an obnoxious beeping sound.

"Well, they didn't try to hide the bomb very well." Donnie sat down, pulling out the necessary tools needed to deactivate the bomb. Raph stood at the doorway, sais at the ready. In silence, Donnie worked, the older shooting him impatient glances every few seconds. The beeping never slowed; rather, the speed seemed to increase rapidly, and the look of stress and concentration on the scientist's steadily worsened.

He held a wire cutter, carefully lining it up in the middle of twenty wires. Just as he made the cut, his hand shook, tearing the wire to the right. Instantly, Donnie realized what had happened, and before he could move, the bomb went off.

The explosion was small by most standards. It didn't even reach across the entire room. It was centered around the bomb and a five foot radius on either side of it. It wasn't until Raph had rolled away, hiding his face from the smoke, that he remembered who was directly in this area.

"Donnie!" He screamed, throwing himself across the room. His younger brother was slowly sitting up, bruised from the explosion but otherwise okay. Already, Raph could hear the footsteps of his brothers approaching, but he was too focused on making sure Donnie was okay.

He carefully examined his little brother the way he had done to them, looking for any serious injuries. Donnie only watched with a confusion playing on his face, and it wasn't until Leo and Mikey had sat next to him that he managed to talk.

"Donnie? You okay?" Leo asked, brushing ashes off his shoulder. Donnie looked at him and, brow furrowed, nodded.

"I-I think I'm fine, but...who am I? And who are you?"
