In all fairness, the resemblance is there. Noirin is just a control freak who can't bear to hear anyone say anything that could be construed as possibly in a vague sense not flattering to her.
People don't get angry when lies are told about them. They get angry when the truth is told about them...and deep down Noirin knows the truth: SHE LOOKS LIKE A RABBIT!! mwahahaha...
OK the second half of that last sentence is a joke...but in all honesty she just needs to get over herself. And this whole targeting siavash thing is not a smart thing to try.
