Luther Gillis: File #521 - S4-E2
Continuity mistake: Supposedly Magnum and Luther have been tailed just after release from prison (the second time), but they have a complete change of clothes and accessoires. They can't be back from Robin's nest, because Higgins is outraged to see the man again on the premises - and really everything about dialogue and situation implies the opposite.

Other mistake: For the first 2/3 of the episode (up until their second prison visit) Magnum is wearing the same watch he had been wearing for the previous three seasons, with a leather strap. For the last part of the episode he wears the pepsi bezel watch with a metal bracelet that he inherited from his father and was the focus of the previous episode and will be his regular watch for the rest of the show, in kind of a retcon.
