Signs of Alien PQ coming back?

I think it's because it's too far from the future. Plus Cygnus herself probably has no idea about it either, not like it'd change anything.

Which one is too far in the future?

Cygnus not knowing could easily be remedied by, ya know, telling her.
I'm gonna pull a Godwin's Law here:
Going into the future to defeat an evil Cygnus would be like someone in 1919 finding a portal to 1942 (the midst of WWII) and deciding, instead of stopping Hitler before he started making trouble, to send troops into the future to stop him after a mess has already been made.

we do, also, reading from the dream fragment story, it might very well be a "possible" future, instead of one set in stone. one thing i liked from LKC and future ereve, is how they seem to have a story of their own, not just "lolbackground just cause just kill her"

also, bing forgot about the event and everything, so it "could" happen again.

I'd attribute the dream fragment story to being an easy way to tell a stretched out story.
But, yeah, it's probably just a 'possible future' (still doesn't make the players' actions make sense).

I forgot that Bing forgot. lulz
Would still be annoyed if they pull a Groundhog Day.
