Nobody on the Avengers team realized exactly how literal Peter Parker’s spider physiology was until Bruce Banner innocently brewed a cup of organic peppermint tea to soothe a headache. The moment the sharp scent hits the penthouse, Peter’s primal instincts take over, sending him hissing, clicking, and scaling the walls into the kitchen rafters like a giant, defensive tarantula. The situation goes from hilarious to downright chaotic when Steve Rogers tries to intervene and discovers the hard way that his newly discovered honorary nephew has actual fangs—and actual venom. A story of herbal tea mishaps, accidental super-soldier neurotoxins, and a deeply unimpressed Nick Fury who really doesn’t get paid enough to deal with the Stark family dynamics, and the New Number one rule is No peppermint anywhere near the teen.
