Canaan Episode 3 - A Trivial Matter

Summary:

Despite the weird beginning, the episode progressing good with the Canaan - Maria intereaction during a amusing city stroll, eating ice cream (Maria HAS a big hunger, huh ;)?) while Maria saying 100 times "sugoi" in every thing (XDD).
We'll see again that girl who was in that "karaoke, cosplay and sex" location and has uncover her "upper parts" to Mino (showing also a tatoo symbol of Ua virus disease), but no in a more normal way, eating a unknown (for me) snack and sitting near and again with Mino. And... she said again nothing. Why?? I hope she won't be a mere "fan service object" next time, but seems not so cool to my eyes for now.
But in Canaan anime action is never missed (or how i see the series). In a amusement park or something, while Maria and Canaan travelling inside a sparkly/"sugoi-ing" (XD) tunnel, occur a problem: the travelling train stops and Canaan go out of this for check the situation. Maria see that kid who had his brother (that old dude) killed by Canaan and so, he abduct the girl which act arouse Canaan. She want save Maria from that annoying kid who has put a clock bomb in her head and also kick his ass very hard, but Canaan discover that Ua Virus give some cool powers and features, such as the old dude of the previous episode who has a old body, two hearts for better resistance and faster movements. After, Canaan kills the kid with some gun bullets and save Maria from the bomb. But.... they discover it was a joke, a fake bomb (this was lame, seriously) and the kid dies saying the bomb was really a joke not a real one. But now it's too late, kid: Canaan's coldness is priceless.

Impression
"Eh? What the hell?" I said when i began to see the 3th ep of Canaan. Why?? Simple: what the heck you put that "fanservice"catgirl in this anime which started very good and promising? I cannot stand this. Why some good anime series begin awesome and continue in a confusing/messy way?? By the way, it's better finish this rant or i'll become annoying XD!
However, this episode was very messed and, in some parts, pretty lame as in the fanservice beginning or at the end with that joke bomb, but still good and i'm always willing to follow this anime for seeing its development, because the plot and some characters are very good, but some things are a little out of place here. Hoping for a better development on the next episode ;)!
