Wow...you protrayed this scene perfectly. Vader is just this onimous presence and young Galen looks like he's either about to turn and run for it or stand and fight. And those two dead bodies...the one on the floor is Kento right?
In the game the Wii cutscene for this was pretty much: "Bstard! I'll kill you!" the Ps3 and XBOX one: "Oh no...what do I do?"
