It's worth noting that this is a bit of an unusual, even unnatural situation - where you have people who have been in isolation from any relationships for almost a year, may have a natural desire for romantic relationships and it's part of her specific role and duty to ensure that this stays suppressed throughout the team until the expedition is over. In those circumstances a strict "no-touching" policy for the whole team (not just her) may be quite prudent. You need to ensure that even someone who after many months of loneliness desperately wants to notice and misinterpret something as a sign of romantic affection is unable to do so.
