Well, I spent about a month cloning frogs, a few years back. Though the there were certain conditions to the mechanics that probably wouldn't apply in this case.

[ It was all about encouraging mutation from the original template, because otherwise the machine would just act as a teleporter. Better than the ones that could source through time, where instead you'd make a paradox clone that would have to travel through time to become the original template, those are just complete bullshit.

But then, she was made with just such a machine. Her entire history is stupid. ]

Most of the clones I've known where time duplicates, so that's a little different. But I understand the basic concept, especially how awkward it must have been when you and Riku first met.
