A non sequitur is a conversational and literary device, often used for comical purposes. It is a comment which, due to its lack of meaning relative to the comment it follows, is absurd to the point of being humorous or confusing. Its use can be deliberate or unintentional. Literally, it is Latin for “it does not follow”. In other literature, a non sequitur can denote an abrupt, illogical, unexpected or absurd turn of plot or dialogue not normally associated with or appropriate to that preceding it.

In other words. Things that Alexander wants to talk to you about that may not necessarily relate to neither theater nor advertising.
