Doing what? Memory errors? [That's the second time Papyrus has mentioned one. But, finally--mostly because his other self is still in the process of getting the information about what Papyrus needs--Sans catches on.]

Oh. Huh, I guess I didn't think about how that'd work with your memory. [Didn't think about it at all, really; spreading himself out like this feels natural. Safer than sticking to one place.] There was a future--present now--where I asked you what you needed, so I just grabbed the info from there and skipped out on asking this time. It's faster.

[Reasonable. Normal. Sans definitely won't be horrified later.]
