  We propose a scenario where a companion that is about to exit a common
envelope evolution (CEE) with a giant star accretes mass from the remaining
envelope outside its deep orbit and launches jets that facilitate the removal
of the remaining envelope. The jets that the accretion disk launches collide
with the envelope and form hot bubbles that energize the envelope. Due to
gravitational interaction with the envelope, that might reside in a
circumbinary disk, the companion migrates further in, but the inner boundary of
the circumbinary disk continues to feed the accretion disk. While near the
equatorial plane mass leaves the system at a very low velocity, along the polar
directions velocities are very high. When the primary is an asymptotic giant
branch star, this type of flow forms a bipolar nebula with very narrow waists.
We compare this envelope removal process with four others last-phase common
envelope removal processes. We also note that the accreted gas from the
envelope outside the orbit in the last-phase of the CEE might carry with it
angular momentum that is antialigned to the orbital angular momentum. We
discuss the implications to the possibly antialigned spins of the merging black
hole event GW170104.
