Hose rolling too!
This stuff is nothing but tea leaf reading, not evidence of anything.
O.J. cutting his fingers and "not remembering" how he did it, is in itself nothing. Until you find out this mysterious bleeding by "coincidence" happened around the same time his ex-wife and friend were murdered with a knife does it become "something" significant.
Same goes with DW (or anyone else) going on a frantic cleaning spree and bizarre zig zag California journey, it is in itself nothing. Until you find out this happens around the same time your neighbor kid goes missing...Then it becomes something that definately needs to be looked into. And after looking into it and finding the DNA and fingerprints fit....Well.
