Was her turn at signal at least on? I guess there wasn't a lot you could do, since the incident happened so fast. Other than not riding in a group.
Reminds me of the situation when you're riding along, and someone traveling in the opposite direction suddenly decides to pass, and so they gun the engine, move into your lane, and start barreling straight at you. Your fate is entirely in that idiot's hands, and there's not much you can do short of swerving off the road into the dirt.
Might makes right in these kinds of situations, and it can be pretty humbling.
