I'm afraid not. Your have to start the game back over to get it. But it's not so important. Even if you don't get that one, if you finish the rest of the trinties, Beat the Hades Cup, and collect all the 101 dalmations then you'll still get the Sercet ending. I'll wait til you see this before I close it.
