One thing I kept expecting to happen in the Alias series, was for Marshall to go back in time and get trapped there -  in the time of Rembalde.  And then have to live out the rest of his natural life in that civilized - yet hardly advanced - period.

My logic was, the technology  Rembalde invented/discovered - was mostly things Marshall was already familiar with. 

Rembalde was aslo very familiar with so many obscure details of things during the period of Sydney's stint as a secret agent.

I figured, the only way Francisco Rembalde could have known all of these things - if he had first lived in Sydney's time, and then later, hundreds of years earlier, in the Italy of the past.

Marshall also looks kind of Italian.  So that too, seemed to sort of fit.

The show did not shy away from fantastic technology, bordering on metaphysics.  So a time travel accident would have been not such a big deal, given everything else going on.

Funny isn't it, how that seems to make so much sense
 - yet simply was not the case?
