Tommy and fused them together which made everything harder because everything they wanna time traveler to somewhere they will fused but when they not they get unfuse because of this mistake XD and HD didn't care so they let be but the reasons why they are the time traveler is because karl had fully forgotten everything because of that XD left him and let him live as a normal human being and let someone else to suffer....
