when Tucker tells Mary....
....that Healey's a murderer - Healey's reaction seems to be one of resignation, like he's been found out. Not sure if there's an alternate script in which the allegation turns out to be true, or if it's just done so that it's more of a surprise a few minutes later when we find out that Tucker's a faker and has made everything up.
Or have I just misinterpreted Healey's reaction?
