Is there some extant rule that any member of Serpent's Hand should be able to just magic themselves out of any jam they're stuck in? Maybe just a headcanon dealy, but I thought there was potentially a substantial portion of their members who aren't even anomalous themselves. And anybody who's "pretty chill overall" can still feel the effects of Cabin Fever when they're locked in someplace with people they'd rather not be.
Really, an idea like this kind of brings to mind certain Serpent's Hand GOI formats where the writers devolve into little sidebar squabbles in the footnotes. Playing up the different, typically opposed, viewpoints (Serpent's Hand vs. SCP Researcher vs. SCP D-Class) forced by circumstance to co-operate, but still butting heads over how to do so, could perhaps be entertaining.
You might check out TV Tropes' page on 'Power Trios' for some ideas on how to effectively cast each character in a role that best contributes to the story overall - Something like the SCP Researcher and the Serpent's Hand member being generally opposed, while the D-Class balances the two (driven by a sense of self-preservation / just wanting to get out). Or maybe some other dynamics that could best serve the article.
