She may look delicate, but don’t be fooled. Shelly now has a pain threshold that Colossus would envy. Acids don’t matter, CO2 inhalation is no problems, and she’s now basically immune to cancer. Since naked mole rats live longer than any other rodent, and humans longer than any other ape, it’s not even clear that she’ll ever die. Shelly also has a strong empathic link to the rest of team, she truly is the kind of leader that wouldn’t ask for something she wouldn’t do herself. She expects a lot, but gives it back in spades, and while monogamy isn’t really her thing, there’s a sneaking suspicion around the base that she and Mantis Shrimp may be making time.
