You cant really say if Don and Grover are alike or not. I compared them as theyre both (sometimes) comic relief characters. Grover starts out as a comic relief character, the funny part of the trio who gets caught up in Percy and Annabeths arguing, but as the series goes, his character gets more and more complicated, with the whole Pan quest. Don, as far as we know, is a comic relief character. I think Don sometimes talked a lot like Grover, with his sarcastic jokes, and stuff.
