It was going to be pointless to argue Percy not stay with her. He had already been hovering so if she had him go back to their room, he would probably pace and honestly, it just made more sense for him to be there. It was strange. With Armand, they had looked after one another, but she was so used to Armand that it wouldn't have phased her at all. He was her brother. And while Percy was indeed her husband and she loved him, she wasn't really used to the idea of people watching out for her, hovering. Had things been different back home, without the lies, she probably would be used to it by now, but as it were, she was still getting used to this specific idea.
"That's fine, Percy."
And it was. Because even though she was used to surviving on her own, this whole thing was rather terrifying even if she didn't show it. And even if she weren't used to having someone watch over her, it would probably help keep her a bit calmer. The worst part of things was the unknown. Oh sure, it could be exciting, but when to her the unknown was certain death if it followed the path she was used to? Terrifying was a bit more accurate than exciting.
At Martha's comment on how she'd be there the entire night if they needed anything, and then saying she would go get the medications and everything ready, the actress just nodded that it was fine. Now she really had no idea why everyone was so bothered by the medbay and tried to fight it when things got to a point where they obviously needed help. Especially given the array of differences of the displaced, between famous faces and immune system issues from time travel or whatever.
It was still going to be a long night, though. Because sterile environment and conviction she was going to die despite the reassurances that things were different here and this wasn't a death sentence made it uncomfortable. But so long as she got better, that Percy didn't get ill as well, she'd be fine. She had to be.
