Remember when "Alias" used to kick ass? I know the golden age didn't last long but it did produce a few vicious, knock-down, drag-out fights. Yes! This is part of the season two finale. Sydney realizes her best friend has been replaced by her nemesis and ass-kickery ensues.
I remember watching this and being blown away (and then being pissed off by the terrible twist ending that followed). So this qualifies as my last "Alias" fan moment.
