Roxy would totally be going to Zanzibar. Probably without consulting anyone because she kind of does that. She may also be doing it in her RxoxV persona because secret identities man. (She...she might also feel guilty since she kiiiiind of did hack a bunch of Zanzibar's transport systems about severe weather warning and worry that there was a connection.)

Not that she believes Charon is innocent, but launching attacks on civilians isn't acceptable. =/ Plus you know, might be good to see what dirt Zanzibar DOES have on Charon, so many birds, not enough stones.
