Just the other day I was watching “Star Trek: Deep Space Nine”, when one of the characters seemed familiar to me - Dr Julian Bashir.

As it turned out, the actor who played Dr Bashir - Alexander Siddig - starred in “The Spy” as Ahmed Suidani. This dark and menacing character stands in stark contrast to the character of the always eager, friendly and unassuming Dr Bashir.

A couple episodes later, I noticed that my attitude towards Dr Bashir changed, and I no longer perceived his friend as friendly. And then I asked myself - would that have changed had I first watched Deep Space Nine?

How and where are emotions associated with memories?
