You are not part of the Catalyst in Control, you replace him. One of his comments implicitly says that he is not eager to be replaced by you. His hologram appropriately disappears when you choose Control to further imply he is replaced. You are the new Catalyst though that creates technical issues people discussed heavily on Bioware forums after Mass Effect 3 came out, like is the new Reaper Shepard really what he or she was in life or merely a new Catalyst with Shepard's personality patterns, the Control cutscenes imply Shepard's death gave birth to "it" and that his or her memories guide it, that sort of implies the new Catalyst is not really the person Shepard was in the flesh, only somewhat modeled after him or her like if you are a Paragon you become sort of benevolent guardian, but if you are Renegade you become a dictator that will reform the galaxy into his own image whether the galaxy likes it or not.





About the drawing, it is really good, but Reaper Shepard could create an avatar in the flesh and assume control of it easily, basically he or she could continue visiting their partner and children in the flesh, have sex and even create more children because Reapers are capable of creating an organic being with implants that they can assume control over and could even make it 100% genetically identical to Shepard. Some people find that idea creepy but it is something that is certainly possible to do when you possess all that hyper advanced Reaper technology.
