Viewers have been (not so) patiently waiting to see when this secret romance of Bohannon's (Anson Mount) will end up blowing up in his face. By the looks of things, the cat finally gets out of the bag in Saturday's (July 9) episode of "Hell on Wheels." For weeks now, Bohannon and Fong -- we mean Mei (Angela Zhou) -- have been enjoying a torrid love affair behind closed doors. But after Chang (Byron Mann) caught Cullen leaving the tent last week, suspicions soon lead him to the truth.

In the above Zap2it exclusive clip, Mr. Chang is hot on the trail of Mei. Wanting nothing more than to push her out of Truckee, he is met with a determined opposition. Most of the series has found Chang behind a desk but it's during this confrontation that we get a glimpse at the man's martial arts skills.

Taking on multiple foes, in a very Bruce Lee-like manner, we see Mei shuffling about in a random building. Sure, it's always fun to watch a fight breakout from the sidelines but maybe this would be the time to run? Just a thought. Something tells us things are only going to get worse once Bohannon catches up to them.

"Hell on Wheels" airs Saturdays at 9 p.m. ET/PT on AMC.
