Well until Ex concludes we won't know for certain if it did happen or not.

And considering the nature of this series, virtually anything is possible, no matter how unlikely it may seem to be(well except for GR and Ophis being together, that will literally never happen, not now and not ever, Ophis would rather die first.)
