When Garak is attacked by Rugal, a Cardassian war orphan who is being raised by Bajorans, a veritable can of worms is opened, culminating in a bitter custody battle between Rugal's adoptive parents and his Cardassian father.
'Cardassians' is a reasonably engrossing and well-characterised story, which gently explores issues of prejudice and racism - the highlights being the scenes between Rugal and O'Brien, who is still having trouble setting aside his disdain for all things Cardassian (as indeed, is Rugal - who has been brought up to hate his own kind).
There are problems however and it's hard to avoid the feeling that the script is ultimately rather muddled and half-baked. The issue of child abuse is raised but promptly (and unsatisfactorily) dropped, while the conclusion - both to the courtroom drama and Rugal's fate - is severely botched and ultimately doesn't make much sense. Still, it's great to see Garak back in what is only his second appearance in the series.
