Ceridwen:
The intent of Snape, McGonagall and Dumbledore at that time was to 
rescue Harry and thwart Crouch Jr.'s plans, so they were all foes.  
Their intervention led to his confession by Veritaserum, and ultimately 
to his soul being sucked by a Dementor.  So I think it shows the foes 
of the owner of the glass, in any given situation.
