SEE!! Look at him standing there all protectively!! She made the right choice standing there with him, out of harms way. He had patronuses and skills and stuff and she had a life she wanted to live.

Lex peered around him at the others that were also ordered to get behind him if they could. Well. She wasn't sure there was all that much room but so long as she was the one directly standing by Mr. Vinteren then she didn't really care. She reached for her wand, though she didn't see how much good that would do and held it at ready. Something would happen, eventually.

Their hands were reaching out but she knew they wouldn't get by him so she felt completely safe. Even if he didn't care about them he was still gonna protect himself and by doing so he'd protect her too. Geddit?

Now to wait for them to be taken care of.
