We KNOW the last two are not "possible scenarios" because our boy "H" would have just said he was sharing a computer with this guy "Walter". Also, IF it was a networked situation then he would KNOW who this Walter was. So, that just leaves the "Walter and Victor are the same person using the same computer" scenario & the fact that whoever this "H" is he is a LIAR! Andy - Las Vegas
