  In this addendum to [arXiv:1402.5674] two points are discussed. In the first
additional evidence is provided for a dual connection between the geometric
length of an Einstein-Rosen bridge and the computational complexity of the
quantum state of the dual CFT's. The relation between growth of complexity and
Page's ``Extreme Cosmic Censorship" principle is also remarked on.
  The second point involves a gedanken experiment in which Alice measures a
complete set of commuting observables at her end of an Einstein-Rosen bridge is
discussed. An apparent paradox is resolved by appealing to the properties of
GHZ tripartite entanglement.
