This was just a dream. What REALLY happened after Kickboxer, was that Kurt and Eric decided to live in Thailand where they opened there own Muay Thai school. Kurt eventually married Mylee and they are still there partying today.
As the first movie pointed out, there was only two brothers. There was never a secret brother. The "brother" subplot was used in the first one, even if they did have yet another brother (man what a cheesy, excuse to do a sequel!), they obviously don't care too much about him as they said in the first one "there's only you and me". I can't imagine Eric saying. "Dad was always on my case. But he made me harder. Oh wait on me AND David! I somehow forget that I grew up with a brother here!" Satcha Mitchell is really weak and wimpy looking. He could never be the brother of Kurt and Eric (as Tong Po correctly states in this movie, "You're the weakest of all the Sloanes". That's no bulls**t. It's true). He's really boring and can't act. I would stick to 'Step by Step', Satcha, because as an action star, you're pathetically weak. Kickboxer was a success mainly for the presence of Van Damme. When you put in an unknown actor who's as dull as ditchwater, you know you're in trouble. It basically confirms that this is not a sequel as the actor you see in the flashback is obviously not Van Damme. Maybe this is another person Tong Po fought that was also named Kurt Sloan (cause the Kurt Sloan we know only had one brother, Eric). When you put in a villain that was already defeated (Tong Po), it's kinda mindless. But somehow, despite being soundly defeated, the movie attempts to show him as "stonger than before (how?)" And if Tong Po REALLY killed Kurt (which he didn't, as I said, this film didn't happen), just bashing him up in the end is not getting revenge. Knowing he is a killer, you can only be satisfied if he is killed at the end and gets what he deserves (which he doesn't), so there's no stopping him from doing the same to David Sloan. I could relate to Kurt, I certainly couldn't relate to this "David Sloan". I didn't know who he was and I couldn't care less. I hope the fans of him were just and p**sed off as I was about Van Damme, when he was dumped from the series. The unexciting presence of Satcha Mitchell led to this being a series of direct to video sequels, which he was happy to star in (being a no-name actor). To most of us he's simply making money by being in Van Damme's movies. He wouldn't even have got to be in those without Vann Damme, so don't you dare think of him as the Kickboxer actor. I suppose if David was killed off and it was revealed there was yet ANOTHER brother you'd call it cheesy. Well I found this too cheesy to contemplate. Like I said, this was a Kickboxer imitator, not a sequel. There is no such thing as a "David Sloane". Just Kurt and Eric who are still living it up in Thailand.
