Dagger From the Mirror (ROTTMNT/TMNT 2012 Crossover Fic)

Trusted, Past Tense

"What the hell, Donnie!? Why didn't you tell me about this?!"

April O'Neil, the one who was currently standing in her own universe, shouted. She was livid—but who wouldn't be? Though there was no official friendship handbook out there, April had assumed that it would be a given that if your friends met you from another dimension, you would be the first person they'd tell. It just made sense. Why the four brothers had decided to wait half a day was beyond her; April knew if she was in their place, their T-Phones would be ringing within five minutes.

So yes, April O'Neil was quite upset.

"You were in school!" Donnie exclaimed, "I didn't want you to have to miss more class!"

With eyes darting back and forth between her alternate self and the purple turtle, the girl couldn't decide whether she wanted to yell at Donnie some more or properly meet herself first. Her gaze finally settled on Donnie, and she chose the first option.

"Are you out of your mind?!" April demanded, staring at Donnie as though he were crazy. "You seriously thought I would rather sit in class balancing chemical equations over meeting myself from another dimension?" She paused briefly, but interrupted just as Donnie opened his mouth to answer. "Obviously I would choose the second option, Donnie, who the hell wouldn't?!"

Raph chuckled, "She's got a point there, Don." He was met with April spinning around to switch the victim of her lecture to him, though Mikey and Leo also took the brunt of the yelling.

"Oh, don't think that you three aren't off the hook either. You all have my number! You all should have told me!"

Mikey pouted. "I was gonna tell you, but I broke my T-Phone again and Leo said it was fine 'cause Donnie probably told you already. I would've told you if he didn't say that!""

Leo glared, and Mikey laughed nervously, but didn't retract his statement. April sighed.

"Okay, well, Mikey's off the hook. But the rest of you-"

"Hey, don't be too harsh on them."

April paused when she heard herself, or her alternate self, speak. The Other April began to speak calmly.

"There's been a lot happening and I know everyone is stressed. I'm sure Donnie was always planning on telling you sooner or later," She chuckled, "Come on, you know how he is. He runs on his own clock; my Donnie is the same."

April paused, looking over to aforementioned turtle, who smiled guiltily in return. She visibly deflated, sighing as she turned around to face her alternate self, and smiled meekly.

"Yeah, I know he would have, but eventually is the key word there." She held out a hand. "I'm, uh, April O'Neil. Nice to meet you."

Other April laughed. "Ay, what a coincidence, I'm April too," She joked, grabbing her hand and shaking it firmly. "Pleased to meet ya too, Miss O'Neil."

"Oh, thank god..." Donnie sighed loudly in relief, over... something. One of the Aprils raised a brow, and the other spoke.

"Uh, thank god for...?"

Donnie chuckled nervously. "I, uh, I'm just glad you two physically interacting didn't tear a hole in space and time or something. I was a little worried about that, hoping it wasn't going to end the world and erase us all from existence or something."

"What?!" Both Aprils shouted, while Mikey yelped in fear and latched onto Raph's arm. Leo stared at him like he was crazy.

"That was a possibility?!" The leader exclaimed, "Donnie, why the hell wouldn't you tell us that?!"
