Yes, Rex reads Mark all too clearly for the intrusive bumpkin that he is. Because of his over-reactive warnings and blabbering, Mark may cost Diana her job, as well as ruin his own opportunity to actually do an investigative report on the Center (why he was sent here). I think Mark may even wind up having to find his own way home.
Again, I do not understand Rivera’s decision to cast Mark as some kind of soap opera Mary Worth personal problem solver. Mark is clearly not keeping his professional attitude at the forefront here.
So where does the story go from here? Will Mark save Rex and Tess from the rampaging elephant? Will Rex and Tess suddenly elope, leaving Mark alone with the tigers and a very pissed off Diana Daggers? Poor Mark, he should have talked it over with Ralph the bull snake before accepting this bad gig. Maybe Mark can find future fame and glory by becoming a professional Reality TV show personality.
