become/will become extinct

Assume, if you will, that the Perlicue decided to become extinct, and therefore went extinct (consider this a direction rather like "east" or "west" or "up" or "down"). Given this, it could come back from the extinct at any time it chooses. Consider the conversation it could subsequently have at a Friday night cocktail hour:

"Oh, yes, we all went extinct a couple of hundred years ago, but damn it all, the cost of housing and land taxes just absolutely went through the ceiling, dahlink. Coming back unextinct was the only economically sensible option. And we've discovered that nothing much has changed. Except the gin went dearer, of course!"

This is, you will realise, at least three very wet martinis into the party ...
