Science talk never annoyed Helena. On the contrary, she enjoyed it immensely, even if it was an area she didn't have a particularly deep knowledge of. Learning was half the fun of science, and she was a quick learner. It never took very long for her to grasp new topics and implement them. "The technology these days that allows you to run such tests without physically cross-breeding the species is simply breath-taking. How long does it take to run such a test?"
Despite Helena needing far more than a simple distraction, she still carried on that part of the conversation. It would at least help to pull her out of herself a bit more. She was in danger of closing herself off emotionally, especially today, but Helena did always find it more difficult to do so when other people who cared were around.
Helena did certainly agree that children should not die before their parents, and certainly they should not die the way Christina had. She felt that twinge of anger again stir briefly, but it quelled just as quickly as Gwen moved the conversation on. Helena could count on one hand how many people had asked her how they could help her since Christina had died. That sentiment alone sent a pang of sadness through Helena again. "Nothing can ease the pain I feel, but it helps to have company." Helena wouldn't admit to it, but she really did not want to be alone today. She knew she wouldn't be alone later, Claudia undoubtedly was going to drop by for a while. But for the moment, having Gwen's company would certainly help.
"Typically I would not turn down such an invitation, but I do not trust myself in a lab setting today." Helena was entirely fearful of getting inspired in a bad way in a lab. She had already gone through everything with the time machine she'd constructed to alter the past and save Christina, but she'd failed. The last thing she wanted to do was to venture down another dark path because she was inspired by something she saw. "If you have time before you must go to work, perhaps we could simply walk together?" Helena's hand came back up and closed around her locket and the ring that was now on the same chain.
