Thank you very much and please - be my guest and ramble away, I'm enjoying every second :D

Götterdämmerung is an excellent word, I just might adopt it. I don't usually write such horrible endings, but I find that lately doom and destruction motivate and inspire me more than romance or even sex.

I tried to emphasize how dysfunctional Jack and Ianto's relationship is, their way of dealing without actually dealing - and I'm glad that worked for you.
