Haha, I knew it! The resemblance between the two just couldn’t be a coincidence. Major spoiler coming up ahead if you’ve been following the subs. Let me just say that Wellber no Monogatari has become amazing with its second half, and this episode was no exception. This one was fully focused at the plot, as Tina meets the second Shinigami Bee. He isn’t the one who killed Tina’s parents, but he does tell her where she can find the real murderer.
It’s in Wellber, which makes it almost certain that Rita’s brother indeed was once known as the third Shinigami Bee. Now that I mention it, Tina has never seen the guy, has she? I must say that the way that the creators handled this was very good. First they introduce the guy, and after that they keep dropping subtle hints that all point to the fact that Rita’s brother was the murderer. It’s so much better than when they saved the surprise for the last possible moment and went with a sudden revelation (Romeo and Juliet anyone?)
And those disguises! There are basically two rumours about the Shinigami Bee floating around, and Tina and Bergerac go and investigate the first one, while Rita and Galahad go for the second one. The latter two need a disguise for that in order to avoid suspicion, and both of them looked so awesome. Especially the sunglasses and new haircuts did it.
