Desmond was not a spiteful person, mainly because he was the type of person who would retaliate immediately rather than put up with insults or aggression from others. However, when it came to the burnt piece of wood given to him by Titania, Desmond, had a grudge against it.
It couldn't be helped; after all, a godly treasure had just turned into scattered ashes because of the piece of wood. To top it off, Desmond still didn't know exactly what the hell the piece of wood was. The scan function didn't even detect the presence of an object when Desmond tried to use it. However, he suspected that was Titania's doing.
Whatever the case, the only thing Desmond knew about the piece of wood was that it was the nemesis of the electrical powers, devouring them as soon as it saw them. Titania didn't say much about the piece of wood either, only mentioning that it couldn't be considered a gift but rather a transfer of responsibility. Regardless, Desmond didn't know what she meant.
