[Okay, with a little delay. Papyrus has to pause in the hallway and stare at the flickering lights of the wall eyes for a few seconds. The glowing is a new feature, to the best of his memory, even if it makes sense that the eyes connected to Sans could be more points for magic leakage.

Is this more distressed glowing, the better to keep the dark away...? But he's not feeling the oppressive weight of death and rot this time. If anything, Papyrus is feeling increasingly energized and comforted by the returned power. Weird! Weird but welcome, because it means he's not struggling with things.

He doesn't bother being as quiet on the way back downstairs, sure that he's making the right call in grabbing light and warmth, and wanting to get it to his brother ASAP. Maybe it's just as well that Sans is doing his best moth imitation on Papyrus's return... It makes it that much easier to plug both things in and start arranging them, while he glances at the phone.]

Hey, don't go dropping that - if you want to be safe, it's safer if I can get in touch with you, when you go disappearing.

[Teleporting off to random parts of the canyon or literally disappearing to float around invisibly alike. An absent-minded gesture towards the phone to show Sans what he means is strengthened by all the power he's absorbing - it lifts and slides back onto the couch beside them.]
