I know what you mean. I stay up much longer than I should, being terribly tired in the morning. But some things (stories/threads) are definitely worth it!
And, please, do try the nfic version. Your "Intrusions" was fine enough. (Okay, more than just fine enough, actually...). I don't know what was better: the nfic scene in itself or the twist afterwards. If you can copy that, I'll like it. And I doubt it's just me.
