I'll admit, I'm honestly perplexed as to just what is up with Asahi. Given that he had is "all according to plan" monologue AFTER baring his teeth to the WoL indicates that the whole thing was deliberately planned on his part. It wasn't a slip of the mask - playing the good ambassador, and then unloading on the WoL was all part of the scenario, not an emotional outburst. There was not a hint of "all according to plan, but I hope I didn't compromise the plan with that outburst". No, it was just "all according to plan". This means that undermining his own trustworthiness was fully intended.
As for the WoL's reaction to the outburst, it left me unsatisfied. When Asahi announced he was a Zenos fanboi, my reaction was more along the lines of smug contempt ("Oh, you poor boy - didn't you know that Zenos was a mad dog that had to be put down? Oh, and by the way, he loved me much more than he ever loved you!") rather than the displayed barely-restrained violence. The WoL is apparently being written as hating Zenos (and by proxy, anyone who adores Zenos), but I just don't feel the same way. Hating Zenos is like hating a hurricane, or a rabid animal - and hating Asahi is like hating someone who worships a hurricane or a rabid animal. He's a looney, deserving of contempt and/or pity, not someone worthy of hatred.
On the other hand, I very much appreciated the fact that the WoL IMMEDIATELY spilled the beans on Asahi's duplicity. There wasn't any schlocky secret-keeping to try to preserve the peace, or whatever drama-enhancing stupidity you might expect to see on a prime-time television show. Hien's and the others' responses to the revelation were pretty sensible, as well: proceed with caution, but proceed nonetheless, since the prisoner exchange and potential peace overtures really ARE a good idea, whatever Asahi's true nature might be.
Still, even this is apparently according to plan. SE's building a pretty tall order with Asahi's and Varis's scheming. I hope they don't let me down!
I was surprisingly satisfied with the MSQ's treatment of Yotsuyu. The characters share my opinion that if Yotsuyu really has lost her memories, then she's effectively a new person (albeit a new person with a lot of baggage).
As for the revelation that Zenos is alive - I don't buy it. I think this "Zenos" is either someone modified to look like him, or a flat-out clone of the guy. (The Alagans loved their cloning, and the Garleans love them Allagans, after all!) Supporting this is the fact that Zenos's "doctor" looked an awful lot more like a scientist than a physician. In either case, though, I get the distinct impression that faux-Zenos doesn't appreciate being used as a pawn, so we could be looking at some betrayal-at-a-critical-moment shenanigans when he finally decides to throw off his shackles and stop playing the Zenos role.
