Almost...
I really don't know why I like this series, or why I'm still watching, but I do know that part of it has to do with me being a huge Zelda fan. I like how you've edited the story so far to work around this "David" character, but there is one thing that is really not sitting well with me.
I know this is gonna come off as a Zelda Fan-Boy type complaint, but... The entire reason that Link had the Triforce piece is that he was the Hero of time. This piece of the triforce had chosen him as the Hero, recognizing the courage he had. True, David has a lot of courage, but he should not be able to hold the triforce of courage unless he is the chosen hero. I can understand the Sword releasing itself to David, since its defensive magic is weakest when it is needed the most, but the triforce has no such limits, and would not have given itself to someone not worthy of it. Zelda was given Wisdom, for having the greatest wisdom of all, Gannon was granted Power, having wanted that most of all when he touched the triforce, and the Hero, having the courage to stand against anything evil, no matter what, would have been chosen by the triforce of Courage.
Even though I'm not exactly accepting your judgment (which I thought was a little off when you declared Link to be dead in the first episode) I will finish this series, to see how you right these problems. In my opinion, there should have been someone... anyone better than David for the choice of the triforce piece, but that is our main character. If you can explain it, I'll be happy with that.
Please, try to explain it clearly... preferably not through David's animated lips ^_^;
