  On the orthodox interpretation of bounce cosmologies, a preceding universe
was compressed to a small size before ``bouncing'' to form the present
expanding universe. William Lane Craig and James Sinclair have argued that the
orthodox interpretation is incorrect if the entropy reaches a minimum at the
bounce. In their view, the interface between universes represents the birth of
two expanding universes, i.e., a ``double bang'' instead of a ``big bounce''.
Here, I reply to Craig and Sinclair in defense of the orthodox interpretation.
Contrary to their interpretation, features of one universe explain features of
the other universe and so must precede the other universe in time. Moreover,
contrary to a crucial part of Craig and Sinclair's interpretation, there are
bounce cosmologies in which the thermodynamic arrow of time is continuous
through the bounce even though the entropy is ``reset'' at the bounce.
