The meaning of the locket was a heavy subject for Helena. It was one she tended to tread carefully around. Sooner or later, she would tell Anakin and show him the picture within it. But for the moment, that wasn't going to happen. Helena's mind was elsewhere, more focused on drawing strength from the locket, even if she wasn't completely aware she was even clutching it.
Helena didn't precisely like turning things to a serious topic, but she knew Anakin knew what it was like to tell his younger self of an unsavory future that awaited his younger self upon return to their world. And sometimes it helped to talk about such subjects with someone else who had personal experience with it. Even though she knew their situations were different, they were similar enough that Helena could be able to gauge how things would progress once she told her younger self about everything. Of course, she knew her younger self was different than the younger Anakin, but she could still form some framework of what to expect.
"Not so much putting off as it's being pushed back. I had intended to tell her after the holiday season, but when I fell ill, that was not an option." Helena took a slow breath. "But now that I am well again, I don't think I should put it off any longer." She really did wish she didn't have to have this conversation with her younger self, but for that to happen Helena would've had to have lived a very different life. But Helena had accepted the fact that there were consequences for the choices she had made in her life, and one of them was telling her younger self about them. Even if this scenario had never before been a possibility, but this world proved to be breaking the rules at every turn.
