No. Their impetuous move would be straight ahead, but they can't move straight ahead, therefore they don't move.
You are right of course
A useful tip for dealing with difficult "lining up in combat" situations is to use the option to line up as soon as possible while moving in the TZ. That often avoids problematic contacts, though I'm not sure it would have made much difference in this case.
So because Wb X,Y,Z don't 'move' they don't line up in the TZ either
What if Wb W was destroyed in de Bd turn........?
Wb X moves his next turn into contact with Bd A.
Wb Y, Z should follow up behind in column.
According to the TZ-rules, while moving in a TZ, Wb Y,Z should line up as soon as possible opposite the TZ-ing element most directly in front.
So are Wb X,Y,Z then in a straight line without bends?
Or do I again miss something? Thanx for all your help.
