  We study further the duality between semiclassical AdS3 and formal CFT2
ensembles. First, we study torus wormholes (Maldacena-Maoz wormholes with two
torus boundaries) with one insertion or two insertions on each boundary and
find that they give non-decaying contribution to the product of two torus
one-point or two-point functions at late-time. Second, we study the Z2
quotients of a torus wormhole such that the outcome has one boundary. We
identify quotients that give non-decaying contributions to the torus two-point
function at late-time.
  We comment on reflection (R) or time-reversal (T) symmetry v.s. the
combination RT that is a symmetry of any relativistic field theory. RT symmetry
itself implies that to the extent that a relativistic quantum field theory
exhibits random matrix statistics it should be of the GOE type. We discuss
related implications of these symmetries for wormholes.
