Richard Rankin as Dectective Luke Nelson
Just saw the two-part Fallen Angels (S18 E3-4 ) with guest star Richard Rankin as Detective Luke Nelson... a complex role he portrayed brilliantly.
I really enjoyed the arc ...would be interesting to see a follow up on how Nelson coped after finding out he killed his father when he was a boy and not his mother (who covered up the truth and confessed the murder at the time)
... has there been any mention of the actor returning to play the character again?
