Could the use of the Konjunktiv I in an unexpected place be used to generate derision or mockery? For example, assume I was writing a gossip piece and I tossed in a "sei" after making my opinions very clear. Would this be interpreted as "apparently, ..." or just a grammatical mistake?
Example: (Regarding Theresa May's third attempt to pass her Brexit deal, assuming I had previously made clear that I don't believe this.)
„Dieser Deal sei anders.“
If it would not be in the way of the former, how might I achieve the apparantly, ..." effect?
What are some other ways to achieve the effect, regardless of the answer to the original question?
