»Forgive me if this has been asked before.....«

In the first Matrix, Neo reacts violently after taking the red pill. ("He's going into arrest.....") What's actually going on?

Another thing: when Neo takes the pill, some silvery stuff starts climbing up his arm. To me, it looks as if he's disappearing from the Matrix. Was he?

And if he was, the kid in Kid's Story would have disappeared, leaving no body for burial..... I dunno

Just curious
CYH

They probably disappear like when they are "phoning home"
The silver stuff was different, because he took a pill to
a) interrupt his signal
b) locate him (for Zionites)

The silver liquid was part of mirror... probably form of going through the looking glass. btw, smithian replication is similar, but the liquid is rather black.
