and before you know it, 
Tempest will be famous!
!وسرعان ما ستشتهر تيمبيست
und Tempest wird sicher berühmt werden.
y Tempest se irá haciendo famoso.
y Tempest se irá haciendo famoso.
et Tempest gagnera en notoriété.
Tempest diventerà famosa, ci scommetto!
e com isso, Tempest será famosa!
и Темпест в мгновение ока прославится!
