I think it is possible the Cobras were planning on ambushing the Miyagi-Do’s at the laser tag fight. Think about it, Hawk is a very smart person: he planned a zoo heist, won a coding competition, and was a nerd who are by definition intelligent. He knew that if he messed with Chris he would require backup. He knew that going into the closed laser tag place they wouldn’t be caught and the miyagi’s wouldn’t have anyway of escape. By then he acts like he doesn’t know what they are doing there. Tory and 2 others show up but how? There are 5 miyagi’s and 4 cobras, that means every cobra has to fight someone and it’s likely someone had to fight 2. How are they supposed to text Tory and have her show up with two friends. She showed up fast indicating that she and her friends were nearby waiting. You may be thinking: “How did she know Sam was there?” she said “LaRusso! Where are you b****!” But I’ve already established that Hawk is very smart and he knew Sam would come looking for them. If Tory has been there when Sam showed up, Sam and the miyagi’s would have ran due to Sam being scared and they were all counting on Sam. Chris even says “Sam!” after being jumped by Rickenberger and Mitch. Demetri says help me and is likely looking for Sam. Demetri likely was wishing Sam would save him from hawk again. Overall the evidence leads to this conclusion and it does makes sense.
