So I'm in the Military Base right next to Lieutenant (saved before the convo). I remember a long time ago watching my friend (and now people online) speak with the Lieutenant and run away from the punch. I do that, just like this guy in the video does http://www.youtube.com/watch?v=WzSOKi_t5fg&t=2m30s with nearly the same path, except if I go too far away from him, he instantly goes hostile and kills me. Even if I manage to get the key to the Cathedral, I can't make it around the corner without getting killed.

I've got the official 1.2 patch and the unofficial 1.3.5 patch, but I was wondering if there's either a secret to it or I'm just not doing it right.

(Not to mention the guard at the front of the base, while normally able to savescumm him into throwing pulse grenades (0 damage), they do full damage to me instead, but I expected that to be patched.)
