Keeping secrets from her husband hadn't worked out well for her in the past. She wanted to be his partner at the very least in the upcoming struggle. At least until she knew where she wanted to go and what she wanted to do, she knew it would be best to stay at Antonin's side. He'd already proven that he was willing to do anything to keep his family safe. And, if she had to be completely honest, she did care for the man in her own way. He needed to have as much information as possible if he wanted to survive. Wasn't it frustrating for her when he refused to tell her what he knew? She didn't want to do the same to him.
