That when the voice over says 'you killed his son' or whatever, and it shows a guardian hitting Crota with the sword, that Crota is attacking at the same time? And therefore not kneeling? So you won't do any damage :p Let me know if you saw it, and what your reaction was. Okay people. I get it. It was a titan. Its a mistake. Is that really your only intelligent response? 'Actually it's a titan'. Yah I know already.
