Another seamless reincarnation with no acknowledgement of the fact that he has essentially robbed this family of their child without them even knowing. It's perverse and morally awful. Is it to hard to make it a gradual merging? Have a scene where you describe in detail the death of Kaiser, how it happened and how death felt. then cut to a young Lukas (<10) and frame the death as a recurring nightmare. Imply that Kaiser's ego went completely dormant at the time of his death. Lukas was born as a fairly normal child which developed it's own ego. As he gets older, Kaiser's dormant ego is starting to awaken and bleed into Lukas', manifesting as nightmares, emotions and flashes of memory he doesn't recognise, bouts of disorientation and dissociation, skills and instincts that aren't his own. It would only take a few chapters of time to do this stuff and have the two eventually merge into one, and with it you get the reincarnation without screwing over the parents.
