entanglement does not allow faster than light communication, but it's also not like your boxes, which have a "hidden variable" (a known real answer).
entanglement is a non-local effect that is deeply weird. both marbles are "bled" (or "rue") when they are put in the boxes. when the boxes open, one becomes red, and the other blue. even though they are now far apart.
(and what this new work suggests, afaict, is that this is no longer so weird - they're actually close together if you go "through the wormhole", but that's just my vague understanding).
