OMG you just ruined the whole **bleep** game for me SCREW YOU!!!!
Ok, let me get this right, you clicked on a thread titled "The Last of Us ending leaked online", then went to a youtube link in the OP that obviously contained the leaked ending, and you blame HIM? Its not like he randomly put the ending in random threads, you knew what you were getting into, he gave no spoilers in the actual forum, it was your choice to watch, and there for your own damned fault.
NOOO!!!! I know I clicked onto this thread and clicked the link willingly, knowing that I'd have the ending spoiled but it's still the OP's fault!!! SCREW YOU!!!!!
