Great episode from start to finish. When they do these occasional stories focusing on specific characters ('Strike' highlighted Connie, 'Just a Girl in the World' highlighted Lupo) it brings a fresh dimension to the show. If every ep. had these character revelations it would get old and tiresome, but so far, they seem to use the right opportunities and get great results (who can forget the recent 'For the Defense" which playfully explored Mike's feelings for Connie).
The investigation was both interesting and emotionally charged- I applaud their choice to begin the episode differently than usual, showing the detectives in pursuit of the suspect, instead of simply discovering the crime. But, of course, not even the tone-setting intro could have prepared one for the shocking revelation about EADA Cutter. Linus Roache's performance in a climactic scene putting his career on the line, refusing to 'plead down' the suspect, exuding the kind of zealous 'outrage' we would expect from Jack McCoy, ended the episode on a high note. For anyone who missed "Innocence", rest assured that it will air on TNT- because they know drama.
