Have you ever worked so hard your entire life so that you may beat that rival that oppressed you when growing up and when you are just almost there, the rival either gives up or turn a new leaf?
The feeling of wanting to get your own revenge using your own hands, and just waiting to be stronger enough to dish that punishment, and when the time is right, you go to avenge your revenge and you find your enemies annihilated. Just what kind of emotions would one feel?
Complicated!
This is exactly how Neal felt the day he found that manor razed to the ground without a living soul in it.
For so many years, he trained, fought monsters, and geniuses, and endangered his life so much that he nearly died several times.
Because of his hunger for revenge, he didn't even dare to go back home as much as he wanted. he was afraid that he will be exposed if he faces his mother, they had lied to her for so many years and he didn't want to hurt her.
