In the opening scene, Eddie gives Frank a surveillance photo of Kelly. The photo is of her leaving the front of the cafe that she frequents and the two will be working. There also seems to be a couple behind her headed towards the cafe.
When Kelly's first scenes come later, she is in the exact same outfit with the same purse. And when she walks out, seemingly the exact same couple pass her going in. This is as if a picture was taken of something that hadn't happened yet.
In the real world though, the cafe scenes were either shot before the Frank/Eddie scene or at least the close-up of the photo in Frank's hand which was inserted in post production.

For Kelly to have been drugged enough from the coffee to barely register a needle being stuck into her foot, the addition of heroin certainly would have killed her.
The heroin in Kelly's system would not have been affecting her to a noticeable degree after sleeping late as she did; the high would have ended long before she arrived at the office.
One does not suffer from withdrawal symptoms - as Kelly did - after using heroin only two times.
Although she isn't shown driving it until her twelfth episode (Cruising Angels (1979)), Sabrina's orange Pinto - seen parked outside the Townsend Agency building - was indeed used by her replacement, Tiffany Welles. You'd think after three years the company could afford a nicer - and less conspicuous - car. Perhaps the fault lies with the notoriously stingy Bosley.
The stunt-person running on the roof in place of Kelly is very evidently a man in a wig.
