User blog:General MGD 109/Double Meaning Opening text

Just something I was wondering, at the beguining of season two, the opening text is, for the first time not a story but a poem, "The Second Coming" By W.B Yeats. Now upon first look the lines "The blood-dimmed tide is loosed, and everywhere The ceremony of innocence is drowned" are taken to refer to the Mauvais Dentes rampage, however upon looking back I can't help but if it has a few other meanings.

I the line about the "ceremony of innocence" strikes me, considering the seasons tone in comparison to the previous one, I can't wonder if its referring to the fact things got more serious (sure the first season wasn't light hearted, but this one was a lot darker) and not the just the season, Nick's character got a lot darker, in season one he was mostly against violence and preferred to talk matters, in this season he almost beat a person to death with her bare hands about three times. This is understandable granted, but I'm wondering if them choosing the line was to foreshadow the coming darkness.

Another possible interpretation I got, was when I considered what the poem itself was about, Yeats wrote the poem in 1919 to refer to the damage done by the first world war had done to the world and to ask if they could continue? I'm wondering if it could also be a refer to that, considering by the time the episode aired they had flipped a lot of things, so could they be asking can we continue?

Just a few things that occurred to me, what do you think?
