User blog comment:Gourgeist/Shingeki no Kyojin Chapter 63 Review: Chains/@comment-24930713-20150104091458

Not gonna lie, I was highly disappointed when I read that they were going the "all Ackermans are related with special abilities" route. :/ So right now I'm waiting to find out how Levi is related to them. But with this reveal I get the feeling that the Ackerman bloodline is also one of those familys immune to the memory affects.

Otherwise I enjoyed the rest of the chapter. I had a feeling that Eren and Historia would end up in this position.

And just my personal opinion, I don't feel Frieda's muscular lining is worth noting. If anything it seems to be a common trait for titan shifters. Considering they're all signifigantly more muscular than the average titan. With the only muscular titan that I remember seeing being in Attack on Titan: Before the Fall.
