I think at some point in development the PC is supposed to have tried to make a run for it when you first pick up your weapon. A couple of playthroughs recently, I got to that point and spacebar'd through it quickly and the point where my PC picked up the weapon, instead of facing off the demon she did a double take with weapon in hand and took off, it then glitch screened and she was back facing the demon.
It's a shame they removed all that and the bit with Cassandra, would have made more sense for you to really be able to resist first off instead of the passive acceptance thing.
