Doesn't mean a thing. Michael has given testimony. People here call it hearsay. Get the picture?
Michael gives testimony that will result in him getting a LOT of money and a chance to marry the woman he is committing adulty with. (Of course he is, because he insists that Terri is his wife. He can't have it both ways)
Nurses give testimony that may result (and does) in at least one of them losing their jobs.
But motives NEVER have anything to do with who tells the truth and who lies.
