Introduction As a longtime fan of Harry Potter, it has also saddened me to see so many of his games be so flawed and nearly unplayable. This isn't the case with this game. Being new to the LEGO video game series..
When you find Margot next to Hercules, shoot her when the screen is fading out (it's hard, but aim the gun away from her as you walk towards her and swing to her during the fade and shoot.) Once the mission begins, you will see Margot and Luis standing and on the steps where Margot was will be her corpse!
