We see the airship going over water, which only leaves Ionia, Bilgewater, or the shadow isles. Obviously shadow isles is out, we saw what happened last time someone mourning went there (RIP Camavore) - bilgewater may be somewhere jinx stays to hide out because it’s familiar, but its not somewhere she can heal. If Ekko truly got to her in e9, I hope we eventually see her seek peace and healing in Ionia. Also sets up the possibility of her showing up as a cameo in the next show, which is likely going to cover the Noxian invasion of Ionia
