Ah, yeah, see, I'm already months-from-now concerned, he admits. Like. He remembers the watered-down feel of the Singularity's defense measures. For all Istredd's continued poking and prodding and wanting to understand, Lucifer's braced for the Singularity to react poorly no matter how respectful Istredd is towards His Rock. Not now, current, concerned. This is me, thinking of our future.

He's future planning on Istredd doing something(s) stupid. The continued 'you need to be careful' extends so far beyond from now.

You have a tendency to be extremely focused in your goals and maybe not see the dangers coming at you.
