I create this topic because I have two main questions about the Titans injections:

1) How did they inject spinal fluid to Eldians before the invention of syringes? If I'm not mistaken, in our world, they were invented about 1850. Let's admit that in the AoT world they were created a bit sooner (in terms of equivalence) and they were already here during the Great Titan War (if they didn't exist yet at this period, how could the Reiss have some syringes with them? So, I assume this invention is prior to the GTW.). But at the time of Ymir? A century after her? Syringes didn't exist at this time, so how did they do? Can the Coordinate transform subjects of Ymir into Titans without injecting spinal fluid to them?

2) What would happen if we inject spinal fluid to someone who isn't a subject of Ymir? I have considered a few possibilities:

- Nothing happens. Their immune system will just have to deal with that amount of spinal fluid aded to their body, just the time to destroy it.

- They could have some infections, diseases, a bit like when we inject someone with the blood of the wrong group

- My last guess, which is a theory by itself: most of times, injecting spinal fluids will not do anything, but what if, one time, Eldia tried injecting it to non-subjects of Ymir... And it worked (c'mon, in 2000 years of history there's no way they never tried such a thing, I would even guess that the Titan's Biology Research Society have tried it with prisoners that weren't subjects of Ymir, seems very like something Marley would do). And once, those injections worked, giving us the Ackermans : that would explain the "byproduct of Titan science" and their link with the paths, the fact that they are "Titans in human form". The fact that the Ackermans are the only known byproducts of Titans science means that it was exceptionnal, it was the only time injections worked on non-subjects of Ymir. (This theory doesn't exclude the intervention of the Coordinate, which I think might have happened during the creation of Ackermans, because linking them to the paths might be something a bit too impressive to be accomplished only using the injections).
