    "A mathematical sequence, and I never guessed."
    "Yes, Kevin, it was you who has sent them away unconsciously.  You choose a destination for each by your walking pattern.  Each square represents a mathematical constant and the variables were your robot friends.  Relocate those positions; it's a simple matter of wishing them back." And Kevin once again has fallen into a robot mind game where winner takes all and the loser oblivion.
