There's also the case of Arthur and Hawk's Mom mentioning an ominous imbalance once he wakes up. And yeah, I'm not buying that the manga's over yet until it's addressed(I wasn't fooled last time and I'm not falling for it now). And the Sins are going to need to take care of the Supreme Goddess since she's undoubtedly going to interfere with Elizabeth and Meliodas' union.
