In Parallels, Worf jumped to other quantum realities when near Geordi's VISOR. Were the other Worfs aware and trying to find answers also? Or did the just move once, and so were not aware as such due to only small changes, whilst the original Worf leapfrogged through realities with greater and greater changes adding up?
Would all the Worfs have returned to the correct realities at the end, eg the one with the children and married to Troi, or would they have remained 'lost'? I ask as in the episode when they contact the original Enterprise, there is a Worf there, but no one seems to have noticed he is the wrong one.
