Well, let’s look at this situation positively: If the lion mauls Rex, Mark knows that the place is truly corrupt, as is Tess. Furthermore, he no longer has to fret over Rex’s mental stability. So, my advice to Mark is “Find whoever is handling bets and place your money on the lion. Afterward, go write your blasted article.” At the very least, Mark should be filming this spectacle. Might be the catalyst for a new Reality Show.
On the other hand, the alleged “rampaging elephant” could show up in the nick of time and stomp the tiger, just before it bites Rex’s head off. I mean, it just has to show up at some point, don’t you think?
