I'm confused. Are they re-watching Five Venoms or watching it for the first time?
If it's the latter then there's nothing to comment about since Scorpion keeps his identity secret for the longest. He doesn't even kick anyone when kills earlier in the movie. So that only makes sense on the first pass if one is watching for the first time and spoiled it too the other: or if they're talking about the scene Scorpion reveals himself by smashing walls at the climax. Literally in the last seven minutes of the movie. If they're in the home stretch then they've seen The Student also replicate Lizard's gravity power.
It may make sense if they're fangasaming about their actors. But I'd expect a namedrop to a different role or movie.
