I know this is very old but does reiner's father really hate him because he show up to his thing. If he really does hate wouldn't you think wouldn't show up at all (sorry my typing isnt really that good)
This is one of those topics that is all personal opinion and conjecture. I personally don’t take his reaction at being confronted as evidence of hatred for Reiner. I think it’s obvious he was terrified, and rightly so. He also seemed supremely mistrustful of Karina. He suspected that she was using Reiner as a way to get back at him. Seeing what sort of person Karina is, I think he’s safe to assume that. But as you say, his presence at the ceremony is proof that he’s at least curious about Reiner and aware of their connection.
Since he worked on the base where Reiner trained, he probably had some access to Reiner. While Isayama kept their meeting to a few essential panels, It makes sense to me that this wasn’t the first time Reiner had seen him. My headcanon is that Reiner’s father kept a peripheral eye on Reiner and appeared often enough that Reiner was able to make the connection that we see in chapter 95.
Thanks for the ask!
