@redenchilada the dialogue of the entire episode confirmed Twilight's strong belief that the CMC's were there for the sake of learning, and when she made that assumption the first time with two friends, the CMC's nodded along - which further validated her belief. So at the end she just believed that, it was simply escalating, or catching on as it were, because kids be like that erryday. while what I'm about to say doesnt directly defend this episode, twilight and gang were far dumber in previous cmc episodes.
