Look, I'm not the type of guy to be moved by just anything, and in fact it's very rare for me to even get emotional about whatever... But the second section of this episode simply did it. What's funny is that I had been wondering if they'd ever have a little dive on Konata's lack of motherly presence, and I think they did it marvelously in this episode. Not only that, but
Konata's visit was something I really wasn't expecting. It only added to the already-dramatic situation, since we're hearing and really getting a glimpse of her for the first time in the whole series and we haven't had a lot of airtime on this topic.
Personally, I had to watch it in parts, because I just wouldn't be able to take it in one shot without shedding a tear or two. The way they conducted the whole scene was really well done, not drifting away from the comic/gag style that L*S is known for, but also becoming serious when the situation needed it. Honestly, I don't have a lot of words to describe the feeling, but right now I'm actually somewhat depressed.
It's amazing what Anime can do, right?
