Him acting like a wimp and being super strong is possible, but it doesn't explain why he thought he should confront the invader alone. As the consummate coward I am, I would not tell the person who knows how to fight to back off and let me take care of it if I know that I am a coward. That is the inconsistent bullshit that doesn't make sense. If he knows he is a coward, then he should act like one, and that includes not throwing himself into danger. Also INB4 someone says "well he didn't know it was a threat," if he is a coward he would not take that chance. He is just stupid.
