Dr. Holloway's dead

When Weyland and Shaw are talking, David movies to separate table and is keeping busy. I want to call your attention to Shaw's eyes just after she says to Weyland: "Dr. Holloway's dead". She doesn't turn her head but clearly looks over to David before resuming the conversation. If a look was a thousand words this would be 1,000,000. To my mind it shows that she knows David is involved with Charlie's death. Based on later tunnel scenes Shaw questions David about how safe the tunnel air is since we don't know what actually changed Holloway. Also just before leaving for the Engineer/Weyland meeting the scene of Shaw and David discussing wanting their parent's dead, contains some looks from both parties that each is sort of playing a game. There may not be enough evidence to suggest that Shaw knew what had happenned with Holloway but the series of scenes shows a marked difference in the Shaw /David relationship from when she was saved by the robot. Then david asks her if she was OK. Now I can't see that discussion happenning after the birthing scenes. Perhaps it is Shaws awakening to the fact that Davisd is manipulating almost everyhing we see in the movie. This is something the movie watchers and posters of this site have long known. And then there is David and Shaw joining forces to help both escape the moon....
