Daniel mentions that someone named Tachyon warned him about the tracking device on his car. Then I saw that in Tachyon's Drop 5 there was a complicated code, which translates to:
GLAD YOU FINALLY UNDERSTOOD MY MESSAGE.
DON'T FOLLOW UP A SMART MOVE WITH A STUPID ONE...
AND WHATEVER YOU DO, DON'T GO HOME.
Is this how Tachyon is communicating with Daniel? Is Daniel smart enough, or does he even have the time to figure out these complex codes (what with being homeless at this time and running and all)?
Additionally, if Daniel can figure this out on his own, then it should be a piece of cake to decode what Tachyon left in Jonas' car.
Now I know this must have been discussed...please point me to the thread...but is it possible that Daniel is Brother or another agent in the Culper Ring? Is Brother actually a person, or an entity or organization (i.e. Big Brother)? Has there been a George Orwell reference? j/k

I posted in the video section that my theory was that the Drew books had something in them that "triggered" Daniel (the assumption being that Op had programmed him). Another poster pointed out to me that maybe the Drew books had deprogramming triggers in them, and that is why Tach left them. At first I thought that was a weird thing to say, but then I spent all night in the AphidPedia, and...well...
Is Daniel Brother? Please point me to the thread discussion of this. I'm trying to get fully involved in the ARG (kept up with some of it), although I don't understand how you all are decoding all this stuff. You guys are smarter than I am. Good work, you all!
