  The origin of gamma-ray bursts (GRBs) is still a fascinating field of
research nowadays. While we have been collecting more and more observationally
constrained properties of GRB-physics, new theoretical results on the
progenitor evolution (be it stellar or compact object) have also emerged. I
review some of the most promising progenitor theories for forming a
short-duration GRB. A special emphasis is put on the hypothetical case of
forming a short-duration GRB through the double black hole merger scenario --
in which case we may expect to observe a gravitational wave emission too. The
chemically homogeneous channel for forming a black hole binary is discussed,
and the stellar progenitors (so called TWUIN stars) are introduced. The birth
place of these short-duration GRBs with a gravitational wave counterpart may be
low-metallicity, starforming dwarf galaxies.
