Who actually killed Wheeljack correct? Either that or I'm seeing things. Sorry I'm just confused first time I saw the movie the whole scene happened so damn quick and I just assumed it was Soundwave like in the books. However I saw the movie again last night and was genuinely surprised when I saw who I thought was Barricade, pull the trigger with Soundwave way off in the background playing no part in his death (aside from ordering it). Needless to say it was a WTF moment for me, since I was almost certain Soundwave killed him when I saw it first time around.
