Had this happened at any other time, Helena might have given more focus to the fact they were fictional. But considering not only had it been Moriarty that she'd found this out from, but he'd used it to start his game with her rather took precedence over the fictional thing. She'd focus on that when she could, but Helena was currently more fearing for her life than being concerned about not being real in this place. Priorities, really. The video itself Helena could largely handle. It was the Christina references within it that got to her. But the title of the video itself also frightened her. Moriarty had chosen it for a reason.
Nothing sent a message like the title of "Going Down Today" did. And for the first time she was facing the potential for death where it wasn't under her control or choice. After all, she'd let Pete try to destroy the Janus coin to protect the rest of them. Then she'd willingly given up her life to save the rest of them from the explosion. But now to know her life was out of her hands was something she absolutely hated. The only thing she could do to ensure Moriarty didn't kill her was to never leave the complex again, but that was rather impossible, wasn't it?
Helena looked back to Myka, sniffing slightly and taking a very deep breath. "I hope she finds him." She almost mentioned that she'd love nothing more than to put a bullet in Moriarty's head, but she kept that comment to herself. And Helena really wished Claudia would find him far sooner than later so she didn't have to live in fear. And really, Helena didn't want to blow up yet again. She really would take being incinerated in Warehouse 13 than getting blown up by Moriarty.
At the comment of not letting Moriarty under her skin, Helena huffed slightly. "And how am I supposed to do that? Myka, he knows exactly how to get under my skin. He's seen my story, and he's smart enough to know my buttons. And frankly, he's all ready pushed them." At which point, Helena went over to her computer and pulled up the post and comments from Moriarty, then stepped away to let Myka see. "Before you say anything, yes I know commenting to him is stupid." Again, she turned away from the computer and ran a hand through her hair, obviously disconcerted by this turn of events.
"And really, how am I supposed to keep him from getting under my skin? He bloody well all ready knows how to do that. I can defend myself from anything he can throw at me except Christina. I have no way to defend myself from that. You know that." And there was no way she could build up enough defenses from such attacks in this short span of time. There was also the fact that her Myka button made her murderous. Which...she should probably mention because she was not going to start keeping things from Myka again. "There's also the fact that I don't have impulse control when it comes to him threatening you." Helena would kill to make sure Myka stayed safe. And she needed to not run off and try to kill Moriarty on impulse, which she sort of currently wanted to do.
