Omg, i just discovered something awesome. A few minutes ago, i watched TF:ROTF again, and finally my favorite scene started: The forest fight. This this is kickass. However, i just realised how much more detailed this scene is. The scene was nearing its end, Optimus takes one of starscreams arms off. However, i always look for new things in the movie, so i focused on Grindor that was walking around. Now Optimus was jumping on grindors head. But then i discovered something.. i looked like Grindor was taking something from his belt, something formed like a knife.
After the scene was over, i scrolled back to that moment and paused the scene. Indeed, grindor was taking a knife shaped object out of his leg to fight optimus. But then it hit me: Holy shit, that is one Optimus Primes blades?? How does that blade came into his leg? I scrolled back to the part where i last saw Optimus with his two blades (the scene where he is turning and hits grindor as well as starscream).
And then... i saw it. Just right after Optimus "rolls" over starscream, he does it...... he throws his blade at grindor.
That... is kickass.
