Hello NinjaGo fans! I have a little theory about a baby that Cole is holding and one of Tommy' posts on Twitter. So, if anyone hasn't watched season 7 yet, then this post has spoilers about it! In the last episode of HoT, Sensei Wu got stuck in the Time Vortex, right? Well, ninjas would find a way to bring him back, but not as an very old person, but a baby! So we probably have the answer about the existence of the child. But why actually Cole is holding it, not for example; Zane or Nya? The answer is in Tommy's Twitter post about three frazes; two of them being right and one being wrong. And there was a mention that Cole will sing in few episodes. And why would he sing? To calm down the baby if it started crying, of course! So, Cole will hold the baby and calm it down instantly, instead of running around and searching for other ninjas who took the baby! I guess that this theory explains both post and picture! Feel free to comment your opinion on it! Sorry for any mistakes, English isn't my first launguage!
