Sam was supposed to be in China. Why would he be named 'Sam' anyway, it is a western name.
And the Labcoin handle really does type in more of a European way... we have plenty of Chinese posters here and they all have a distinctly different way of typing.
I really think that Sam = Alberto/Alessia
Yes this is pretty certain. Fabreezio also knows alot more about this company than he leads us to believe.
