u do know h4n is s good actor tho, right? anyway, watch the rehearsal fanvid from london fes and then their goofy shenanigangs at the concert, they did "rehearse" as in the general outline. nobody screaming it's fan service. it's like w the c1rcvs skit for jp like, they roughly all discuss what theyre gonna do and then go with the flow. no need to get angry.
also no, that doesnt look genuinely surprised. you're like my colleague who tells other ppl what they felt or thought because she knows better...
