Ah, nice work if you can get it, Elke.

Where in the El-ke is Niki?

What happens to Niki? She's missing from quite a few episodes, even though she remains in the title sequence and is credited on IMDB for all of the series.

Did Rex throw a jealous hissy fit and get her removed? Did the female viewers complain that they preferred Marc without any love interest? Or did she overdose on the Wurstsemmel and gain a few kilos? Hmm. What's your theory?
