Satsuki and Tsuchi remind me of my brother and me. It gave me a weird feeling to have it feel so close to what we have. I definitely have a brocon, and he's pretty good at reading me, but still manages to piss me off at least once every time he visits. :)
Hiiragi's "polygamy is punishable by law" line at the beginning was hilarious.
Did anyone else notice the incredibly dirty looking gesture Tsuchida displays, acting from embarrassment as he tries to explain how Sakura was the neighborhood boss and would drag him everywhere back in their past? I mean you even hear Anzu's voice there! Funniest highlight of the episode, couldn't stop laughing! xD
Maybe it's only because Satsuki reminds me of Kirino, but she seems to be fond of her brother a bit too much. I'm pretty convinced Tsuchida was in love with (or at least had a crush on) Sakura, that moment at the river was quite telling. I wonder if there will be some kind of closure with Yamamoto by the end of the series, but knowing that it's Gainax, I won't hold my breath. 5/5 for the episode, very entertaining one, especially Hii-chan as usual.
