Both Terrified and When Evil Lurks have an older woman character who shows up with an elaborate pseudoscientific-looking instrument that can be used to contain the spreading evil, but, like, it takes a really long time to set up and actually everyone has to kind of get out of the way while it's being prepared and there's no way to explain why it works to people with no relevant knowledge, and, um, yeah, that's vaccines. That's counterterrorism measures. That's climate science.
