Definitely a spoiler, but maybe not as big of a spoiler, still a spoiler... I remember when I read it, I always thought of Ymir as a pseudo-god character... (and male lol.) So I was genuinely surprised when thingy calls her Ymir after the sidestory. (I'm sure that's also the reason Isayama purposely keeps her name secret until after the 18.5. Funnily enough, Ymir wasn't part of the Top 10 either despite her potentials and what Christa says, in which case is also a factor that facilitates the name secret.)
Having said that, it's not so much a spoiler anymore if your friend knows Ymir's name... To be precise, Ymir's name is more of a spoiler than anything else...

This tweet was actually from mid-August. The first sentence's referring to sorting out Ch49 stuff, but the second says something like:
"We've also sorted out the 'long plot' that paves way to the ending, it was a good day."
......
Ending????? SnK ending soon or, is Isayama just planning so much ahead??????? This is freaking me out.
