That is an important detail.

Another important detail is that at this point there is still no confirmed way of killing a titan shifter other than having another titan eat them and ingest their spinal fluid. The only other implicit way to kill a titan shifter is to have them die from old age or starvation.

So, maybe someone will have to take one for the team and eat Reiner's body because who knows what's the deal with that guy.

Someone's going to get the titan serum though, Levi having that titan serum is definitely a major chekhov's gun in AOT.
