And, since the HHH that DDD calls will abort is emulation, it WILL return to DDD and it will return also.

The emulation stops, and the emulating behavor of HHH stops, but not the behavior of the input.

When DDD is no longer being emulated all of its behavior

Nope, the emulation of DDD may stop, but the BEHAIVOR of THE INPUT, which isn't dependent on the emulator looking at it,
 That is a stupid lie. In input is a static string when not
emulated and only becomes a dynamic process when emulated.
*Anyone with anything like a BSCS would know that*
 
Nope, that CAN'T be the definition of the "behvior of the Input" but of the behavior of the "input processed by this machine". "Behavior" is a term used on MACHINES (so in the above case, the machine is the DECIDER, not the input). When you talk about the "behavior of the input" that needs to represent the behavior of the machine the input represents.
You just don't seem to understand the basics of the field, because you your enforce ignorance.
