Okay. I realized that I never actually spoke or even thought properly about how I see Aya-Yukako-Koichi-Rohan love square (or whatever it is…). So there are some sketches to show the whole picture.
Rohan has unhealthy interest in Koichi. Not sure if it is love or more like performances of some spoiled child, who needs attention, but let him be. Unfortunately (?) for Rohan, Koichi is straight - yeah, I guess so - and dating Yukako. Aya is just catching lulz. And slightly seduces Yukako incidentally LOL. Which is OK with the girl who admires Aya enough (as example to follow) to be ready for some useful experience, if you know what I mean… I like imagining the situation where Aya crosses the line of fun and starts liking Yukako. But Koichi and Yukako ends up dating anyway HAHA.
As a conclusion we have one sweet couple and two broken hearts. BUT WE MAY NEVER REACH THE CONCLUSION IF WE DON’T WANT TO.
So Felicity will make a deal with Helix to get rid of Promy & Talia is the head of Helix, she wants Felicity to be permenant part of Helix & maybe head some day after her. Its like S3 while Ras wanted Oliver to be Ras Al Gul after him, now sort of same storyline is happening with Felicity. Just like Oliver, Felicity will scarifice herself for time being then later expose Helix to the world but will get herself tangled in that mess too, then she Oliver will leave for island becoz WANTED!!
