I'm so amazed and in total AWE of this current Female Titan arc! Who else is in love with these last four episodes?

Perhaps it's because it's been a month since I've watched SNK, but isn't this so intriguing? Perhaps the only thing I think might be a hole in the plot, is how Captain Erwin knew about her, and hence was able to lay a trap. My guess is he somehow encountered her or saw her from afar because anyone who tried to relay a message about this titan got killed. Also, it's great that Armin, Erwin & Levi concluded on their own that someone was inside the titan, from their experience with Eren, but this just makes me think that the Colossal titan and Armored titan are also manipulated by humans, because they also exceed in intelligence and strength. Maybe it will be the case after they find out who the spy is. How did Erwin even think it was possible for the titans to have a human spy? Another thing that should be explained.

Regardless this anime is still perfect.

What do you guys think?

Let's not forget about Eren's father. He's still missing, and I'm sure he's alive outside the walls.

She could be almost anyone considering they could have sneaked into the borders during the prior attack. I'm still wondering if Eren's father has sometime behind it. The thing that gets me most confused is why humans would be teaming up with titans to take over the walls.

Can't think of any advantages of attacking an isolated society that doesn't leave their borders. Unless the only reason they have been attacking this whole time was to hunt down Eren. But even so Eren has been in the middle of battles and the Titan don't swarm him, which makes me think there is something even more important in the walls and Eren is just an obstacle in the way.

I am also thinking Eren's father could have something behind it. 

I also agree that it's puzzling that a human would even think of teaming up with titans to kill humanity because they don't get anything in return, unless they want to be a titan themselves...? If there is something that's being hidden inside the walls, it would be a total shock, and in my opinion not in a good way, at this point because there hasn't been any build up that may lead to this. It's still possible that they want Eren though, because remember how the female titan was hunting him down? She only wants him. But other titans aren't as smart as her and colossal & armored titan, so it's possible they wouldn't comprehend if they were ever given orders, if that's even possible. Don't you think it's odd that she killed anyone who tried to get in her way except for Armin, and anyone who was with him? Do you think it's strange they have the same hair cut, hair color and eye color? Maybe Armin is related to that spy. After all, we have no clue about his parents, or I just can't remember what he said happened to them before his uncle (or grandpa? lol) came into the picture.

Episode 21 was just insane. 

Episode 21 was incredibly brilliant! Every time I think it can't get any better, it does.

I'm so excited for the next episode. I think I might just go at least two weeks without watching SNK because I want to watch more than one episode at a time. I'm so curious to know how it'll end, because it's episode 21, and although they're taking advantage of their time, it may be possible that this series will drag onto a second season.  Or rather third season.

Wow, I think I figured out who the female titan is.

His father has to be involved in this humans-turning-into-titans business. There has to be a link. We need to see him again, or that'll be a fail on the part of the mangaka. 

I just finished the episode like over 15 mins ago and its still got me thinking!

EDIT: Ok, I have an idea about the armored titan and who it may be. I have to share.
