For this third installment, I’ve put together a list of comics that address problems of evidence, authenticity, and doubt: who you can trust, when your cute alien design has been replaced by the real thing, and which of your comrades are as treacherous as “activist” celebrities. What threads through these stories is the proliferation of half-truths, knock-offs, and doubles — and an accompanying sinking/creeping feeling. Each piece approaches it differently, but I can wholeheartedly recommend all of them for your 2020 reading.
