Woah at 0:19-0:20 in the first picture, it shows Harry turning his head, right? Well we saw that in the recent trailer and his face had no blood, but here his nose is bleeding and the area under his bottom lip is bloody as well. Even Hermione hands are covered in blood again.
I bet in the full length trailer that came out Monday, there were moments in their that had a lot more blood, but WB decided to take it all out for that trailer. Makes me happy they didn't just delete it all from the film.
