I just saw this picture on Mugglenet. Look at it and then look at the one we've seen before. It could be that they're just from the same scene OR, as I suspect, the one with just the kids could be what's really happening and the one with Snape as well could be what he's describing to Dumbledore, Fudge, et al. afterwards and not being 100% honest about it. I hope so. I don't want them to change too much.
