But if they did go to the Submachine, was it the wanted results or byproduct of Von Toten machine? Or was the Submachine already existing and Von Toten created the machine for one reason and then discovered the Submachine world with that same Machine?The Abacus wrote: They went to the submachine
No, they probably went somewhere where the Germans can get to them. We can safely assume that Kara is still part of the M-I6.
But if they did go into the Submachine, I wonder if Von Toten already had an exit put on the other side of the projection? Because Kara smash the one they were using.
