Hayate no Gotoku! Can't Take My Eyes Off You - Episode 4

So it begins here, four episodes into the new anime series.  This post will cover a summary of this episode and some reactions.  Due to the fact that this post is fairly lengthy the main body will be after the jump.

This was a quite good episode in my opinion.  At the beginning some of the plot was revealed, mainly the Tsugumi Ruri is looking for the black camellia which apparently is a counterpart of the Shirosakura.  Then, Tsugumi tries to find something to get closer to her "sister" Nagi for essentially the rest of the episode.  She gets told by Hayate that Nagi is into video games and both Chiharu and Kayura recommend games that Nagi has played already, leaving Tsugumi quite a bit poorer and Chiharu quite a bit more secure in her work.  Hayate brings Nagi out to Akiba to talk with her friends and we see how obsessed with her hobbies Nagi is.  Around here the connecting theater happens and everybody (well everybody on the reality side of the screen + Sharna) is reminded that Fumi is a special type of intelligent/stupid. 
Sakuya and Isumi appear in part B connecting theater, but I still don't know why Saku has bluish hair now.  Now Nagi and company move on the a place that sells anime.  Nagi recommends some old stuff she likes and shoots down Kayura and Chiharu's ideas.  Hayate recommends multiple anime where the main character dies or becomes a transcendental force at the end.  Tsugumi finds out the real cost of anime is extremely high so everyone gives up on anime and moves on to find manga.  They end up at Wataru's new store, making this the first appearance of Wataru and Saki in the new anime. (Probably).  Nagi, Kayura, and Chiharu make recommendations for Tsugumi, but Wataru doesn't carry anything they mention.  Tsugumi decides to find a manga for herself and manages to wander into the adult section.  This messes up Tsugumi's perception of Nagi, but she is able to find a manga she wants, the one Nagi made (although Tsugumi doesn't know that).  In the end, Luca/Ruka still seems to be playing the part of a chorus like in many ancient Greek plays, hopefully her role will be expanded into the main story or at least into having a longer and slightly less cryptic chorus time which seemed to happen a bit in this episode as the metaphor seemed more applicable.  Sadly, Ayumu didn't make an appearance; I hope she makes an appearance in the next episode.
So, this was a very enjoyable episode as it in all honesty just was.  I hope that episode five will be just as good. 
Postscript: I forgot to mention the intro music which I quite like; it may not be as fantastic as the intros to the other seasons in pure music, but it fits well with the animation for the intro and really fits with the anime overall extremely well.
