Brielle lied to her cousin about her relationship with Luke and denied her help when she needed it most. I want Brielle to be happy, and god knows she's clearly been through enough already. If that monster you won't name gets anywhere near her, I'll be the first to volunteer to deal with him. But she made a bad decision, lying to Wren and omitting information. Because of the way she went about things, Wren still thinks Luke is going to run off with her any day, she mentions it all the time. Brielle did much to wreck the nascent happiness I saw in that girl, intentionally or not. She isn't a saint, nor is she blameless, and we all have to live with the things we've done.
