Everlasting - S5-E11
Continuity mistake: Oliver puts his vest on over his white shirt to leave the station to help Andy search for the fugitive. A jacket is never in sight. He is shown throughout all of the following scenes in his vest with white shirt. They apprehend the fugitive and return him to the station but Oliver is now wearing a jacket when he gets out of the police cruiser. When he goes back out on patrol, the jacket is missing.
