I think that they are Grimmjow (or misterious guy who killed Quilge) and the other one might be Nel (Urahara may have brought her back to her normal form)or Urahara might have called Yoruichi (or someone from the store) or it might a Hollow that they have met (I would like if it was a Vasto Lorde because they are visually stunning)
