I noticed in the recent image of Starscream he seems to be spitting on Sam... http://iesb.net/images/stories/productionstills2/paramount_summer/sf010.08190.302v01.jpg If you take a look at the first superbowl trailer, at 18 seconds, there seems to be some kind of spark coming out of his mouth. could this be scalpel/the doctor? the children's colouring book did suggest that when sam is pinned down by megger's hand that scalpel is on top of him, this looks to be true from the new hi res shot of scalpel. so what is coming out of starscream's mouth? any ideas?
