Serena quickly picked up the dress she was working on and then went inside Leonard's room which she has been using these days. She changed into the dress, quickly fixed herself to look more presentable, and then grabbed the cloak which she used last time.
She contemplated for a minute or two, then decided to grab a pen and a paper. After she leaves, whether Charlton accepts her or not, she won't return here so she should at least write a letter to Emily and Leonard telling them why she left and that they shouldn't try to find her. On the other hand, since she couldn't face Geoffrey no matter how much she tried to prepare herself and be brave these days, she decided to apologize this way. She wrote everything she needed to apologize to him for, from the beginning to the present, she also thanked him for everything. When she was done writing, her eyes were already red and so was her nose.
