An overview can be found on the episode 4 review.
Right, so the baby ‘went away’, Rin is beign manipulated which is somehow a problem even though she was being manipulated by Eiji in the first place, and despite being able to dominate everything Eiji continues to suck. Plus there’s a whole Darth Vadar/Luke Skywalker thing being set up. None of it makes sense. There’s a completely unnecessary bath sequence for the girls. Rin sums it all up nicely mid-episode when she asks “What am I doing?” At least someone finally called Eiji a dimwit.
And I managed to keep under my 100 words, probably because the question I’m going to ask is why am I still watching this?
