We make a preliminary investigation into twisted A2n theories of class S. Contrary to a common piece of folklore, we establish that theories of this type realise a variety of models of Argyres-Douglas type while utilising only regular punctures. We present an in-depth analysis of all twisted A2 trinion theories, analyse their interrelations via partial Higgsing, and discuss some of their generalised S-dualities.
