It was, but not as wrong as playing out a private conversation in a public forum just to try and get a reaction from Fiona.
How do you feel about your friend Witty trying to hurt and humiliate Fiona by saying she has a "meth face"? How does that make you feel knowing how much she has fought and struggled to get where she is today? How does it make you feel knowing that she shared that struggle with you personally, and he continues to mention it in an attempt to further hurt and humiliate her?
Inigo isn't an avatar, she is a girl. She is a girl who has lived through troubled times, a girl who relied on your friendship when she was at her lowest. A girl who you were once very fond of. I seriously can't believe you made his unacceptable behaviour acceptable.
What's done is done indeed.
