what fun is a dull and boring scientist unless there's spice added to the whole circus show! i personally like the lightman role the way tim is playing it right now, getting a smarter ass day by day, and do notice that all the humorous talks and interesting conversations always involve lightman!
What I understood from the episode is as follows:
Lightman helped Zoe in Jason's conviction as it was her first case, at which time he found Jason guilty of the crime he had committed (i.e. Rex's murder).
After 17 years when Jason was being put to death, he said he did not take Rex and in fact Pied Piper took him (remember he never said that he did not kill Rex). At that time also, Lightman's judgement was correct because Kevin had actually taken the child and had Jason murder him.
So Jason was never an innocent man, and same goes for Kevin when he decided to abduct and murder Oliver.
Hope that solves the mystery!
