If the seasons tittle is accurate the invasion would bring them out of retitrement any way. As I could not see them siting on the sidelines during such an event.

It dos seem that thier is more to Wally amd Artemiss desicon to "reitre" then just wanting a normal life. But what is it? I do think it had some thing to due with the events surounding the death of Tula.
