I am not sure about this, but I think and I have the feeling, that April Derp and Krutzen will make an appearance in The Kraang Conspiracy. Well, I just want to say that Krutzen was a journalist that was studying the disappearance of a scientist, until he found out about the Kraang. Then he talks to the Ninja Turtles and April O'Neil about the aliens' history of themselves and the Mutagen. I think of that because in the trailer, April and the Turtles are seen in a place with a lot of things, which looked like Krutzen's from the Comic Con clip. Also, I think April Derp will appear in that episode. I think that because in the trailer, the Turtles and April are escaping from something, which breaks the wall. Then I noticed that April had the same clothing as April Derp. Then I thought that the thing that broke the wall was April Derp. I think that when April is with the Kraangs, that they cloned her, maybe to see if it copied April's mental energy. I am not sure. What do you guys think about it? If not sure, watch the video to see if you see something that I might be wrong.
