So Ghika is so pissed off that she threw a cup into the TV screen and broke it. Meanwhile I doubt we will see this henchman again, as per Ghika's "No second chance" policy.
I begin to feel, just my guess, that Ghika was turned unwillingly by Aria originally (if you recall there is a scene in a middle east desert with everyone dies except a child). Ghika's full name is Arabic. Being that young as a Lilu can really screw up the person who is essentially a child. And if Aria taught Ghika about being a predator, but then turned around and not being one, then Ghika might felt being betrayed. There are lots of reasons I can think of this hatred. Also, Aria might have felt guilty about Ghika, and thought that committing suicide was the only way to repay Ghika. Anyway, my guess is probably nowhere near the real plot.
