Someone over on the Classic Marvel RPG site pondered whether or not the Thor present in CW#4 would be the Thor we would see in the upcoming title.
Here is a thought that flashed through my mind...
The Thor clone was made from Thor's genetic material, and is physically identical to classic Marvel Thor, but lacks the classics "I-stuff"... the personal history and characteristics that make Thor Thor.
Now, metagenetics postulate that memory, personality, et al. are interlinked with genetics. So, maybe, this clone will serve as the vehicle for Thor-Thor's return? It will at some point "Awaken" to his experience and "Thor-ness", and become what he use to be... as opposed to Stark's newest gun.
Thoughts?
