According to Dudley's clairvoyance ability, Kitty will be married with Eric in the future. But, when Dudley is about to reveal more information about it, he is interrupted by lightning that causes him to go back to normal.
However, Dudley's line "But my name is not Eric" after he is back to normal could possibly hint that he is the one who is going to marry Kitty. The fact that Dudley sounded like he was going to warn Kitty about a major detail concerning who Eric is might hint that he's really a villain or just generally a bad person. However this can't be confirmed until a possible future episode explaining this detail.
