He was a Greek terrorist, which would really have been topical at the time of his reintroduction with the banking crisis causing civil unrest on the streets among factions. Hell, I saw someone commenting as to why the WW movie was shot in Italy, and how DC/WB could have created jobs in Greece. This also would have made the use of Greek myth more topical and arguably organic, especially after following the Greek myth heavy Azzarello run. Either I'm the greatest writer ever (ha!), or his reintroduction was not given a lick of thought.
