I agree, Scott would have insisted on going with Cable to rescue Rachel. It's an editorial mandate to keep Scott from knowing his daughter needs to be rescued. I know if Scott actually knew that Rachel had been taken by Ahab he would have gone with wifi to get her back.
It seems like all the stories are merging together form X-Force, Uncanny, and AoXM. I can only see this getting addressed in AoXM Omega though. Unless they get addressed in Uncanny 22 and AoXM Omega so there are two comics to bring everyone back together. I know there is only one more issue of X-Force remaining and they have a lot of story to wrap up to get everyone where they need to be for HoX/PoX so I kind of wonder of X-Force 10 rolls into AoXM Omega or Uncanny 22 to bring those characters back to the present.
