Once again, Ceru, I really enjoyed this chapter. You're really doing Riven and Lux justice in your writing.
I was only slightly disappointed with Riven's confrontation with Irelia, but perhaps that's just because I believe Riven had put that part of the past far behind her, and locked it down. Or perhaps I kind'a wanted to see Riven get pummeled a bit before finally giving in, weak, confused and shattered emotionally and Irelia just pats her head and comforts her. I don't know, but it just seemed a bit lacking.
Regardless of my own personal outlooks, it was a highly enjoyable chapter! Once again, I'm waiting for the next chapter eagerly. :]
