When Nesta found out that you were her mate she started to purposely move away from you. Already It was already common for Nesta to treat people without thinking about their feelings, and knowing that she was somehow eternally linked to you made her scared.
Nesta I told you that I hated you, that I would never be with you and that I didn't want to know about the bond between you. She carried her cool demeanor and didn't let anyone interfere with her decision to stay out.
She ignored all the effects that the bond could bring and when she started to hear your thoughts and have her own ears for you, she almost had a breakdown. She learned to build a shield around her mind so you couldn't read her thoughts and vice versa, specially when she saw you in that tight training outfit that made your breasts pop.
One day Nesta was at the night court looking pissed after dinner while she is sitting near the fireplace while the inner circle dance and laughs in the main room. She had a bitter feeling about you that was growing inside her the whole evening, and when she arrived at the dinner with Elain and you wasnt there, it got worst.
And she wasn't wrong, because an hour later she was leaning against the door watching as you were passed out in bed with bruises on your face and bandages on your arms. You came back like this after a mission with Azriel, you ended up getting hurt in the process.
She was feeling worried, something she had never felt before and even ended up letting her mental shield to crumble.
Nesta looks at you as you move in bed a little while the rest of the inner circle talking in the living room, so it was just the two of you.
You are such a reckless idiot. Nesta says with her cold face, but her eyes have a little bit of concern that she was trying to hide.
