It's two and a girl that can copy abilities. Besides at a superschool this large it wouldn't be to unusual for there to be people with the same or very similar powers.

And the girl that can copy abilities is currently telepathic. So three telepaths. I was including Mark in the four, as he has a telepathic connection to felines. 

I don't particularly care how many telepaths there are and clearly neither does Allen, which is what counts. It's just that three consecutive posts about mind-reading are unlikely to capture my attention, so forgive me if I miss any information via skim-reading.
