WIth open arms

Hey guys, been coming here for months, this is my first post, I couldn't contain myself any longer lol. At the 46 second mark on the IMAX trailer, someone is walking towards and up onto the platform of what I'm assuming is the Prometheus. Hard to tell who it is, maybe Vickers? Anyway I was wondering what everyone's thought's are on this. Is he/she walking back onboard arms outstretched, about to put them above his/her head as in "I'm safe, it's not me" or is it a kind of "I've learned something and I'm here to share it" arms outstretched?
