There is that. His relative distance from it all, and somewhat questionable ideas of what childhood entails... Might help him not-panic at some things.

For now, Reira's clones may be smaller and younger than the other human child he's fought before, but they make up for it in numbers and tenacity. Papyrus glances each way, focuses his blue magic, and waits.

"You're kidnapped and doing bad things! I know how that goes," unfortunately, "but... No, it's not important at all! Freeing you is."

Once the clones get close enough to him that they're swinging or lunging, Papyrus reverses gravity on himself as hard as he can, to shoot himself up in the air while they run into each other.

If he's really lucky, maybe they'll get mad and fight each other? Not likely, but boy oh boy can he hope.
