When I saw Nick smiling I freaked out and idk, now I think that b4stard stole Nick's data or something (probably not, but I can't help but doubt him; I hope it wasn't Theo tho and I hope Nick won't play dirty but I guess he'll do so, so I'm kinda excited about it xD). I'm so worried about baby Louis.
Conspiracy theory: Imagine that Nick has always wanted the family business but he saw his lil bro's potential and thought he could be dangerous, so then he started to abuse him, isolating him from his family and anybody else, gaslighting him, making him believe the one with the problem it was him, and so on and so on.
