So UAs come from *everywhere* outside of the shell? Or are sending something back to everwhere outside of the shell?
I genuinely can't understand why the last few pages have continued expanding on the idea that the UAs/UPs pointing away from Merope by virtue of the fact they actually point at it is somehow significant.
It's like arguing a coin that came up heads should be thought of as landing tails-down:
Logically accurate to a point; but utterly illogical in the realms of common sense.
Please take some virtual rep.
