Selkie's issues with cold (and by extension all sarnothi) aren't an intolerance so much as a need to avoid hibernation during winter-level temperatures. It's especially important on the surface to avoid hibernation states, because fluctuating temperatures can pull them in and out of torpor, which isn't all that much fun.
Initially I had Then bantering with the two new sarnothi in the final panels, but got to thinking about the reader comments about Selkie breathing in a wetsuit and a funnier idea came in my head. Thanks, everyone.
Selkie knows how important first impressions are. After all supervillains are like puppies, you need to establish dominance early or they’ll wreck your property.
Thankfully however, very few supervillains poop on your carpet.
