It did take me a minute to figure things out, lol. Part 3 will be up this Wednesday! I may just do a fail counter in the video so it's no too short, it did take some trial and error for me to get right.
And thank you! It slipped my mind entirely. Been a while since I watched any gameplay of the first Deadspace (original or the remake) since I never fully beat the game myself yet. At the time I was trying to remember his actual name from the experiment logs.
