B) There's the risk of creating an Abnormal Titan that would target the area with the most people (just like Titan Rod) if only half of the serum is taken.

Well, I don't want both of them to survive (it sort of entirely negates Levi's decision of who to save, and renders this chapter meaningless if they both survive), but I have seen some people online point out that the Serum Levi has comes complete with two needles: I've seen this detail floating around as well, but others have pointed out that syringes like those are required to come with two needles in real life. One is for taking in the liquid from the vial, the other is for injecting it into the body. Using the same needle for both tasks risks bacterial contamination and such.

Wait, really? Damn, if so, then Isayama has a great attention to detail for stuff like this.
