Patrick Wilson, my little idea.

Shaw's crying: That's just an anthropologist geeking out on the most awesome and significant find she's ever encountered. It's a very valid human response, but I wouldn't look into it more deeply than that.

I was just thinking about this ; I believe Patrick Wilson will have a part in Prometheus 2, maybe in flashback scenes. But it would be good if the engineers home planet was actually Heaven, and the dead/Angels lived there. Shaws Dad helping with experiments of Goo. Doubt that would ever happen, but Patrick Wilson cant be settling for 30 seconds screen-time, unless he just jumped at the opportunity to work with Ridley Scott.
