Such a perfectly played series.
>The reason that the Professor was asked what made him rob a bank, how he illustrated his father's death Berlin was also puzzled about the whole story line.
Bringing down to:
-The motive
-Dedication
-Timing
Commitment
>How civilised Lisboa & Sierra were, both knowing how smart, genuine and loving the professor was but they gave each other a respectful and genuine handshake. Regardless of how they both had developed some affection towards him.
Passion & ambition works miracles.
