Hiro was trying to convince Ando that he had traveled to New York 5 weeks into the future, he pointed to a panel in the comic that showed the conversation they just had in Ando's cubicle. My niece pointed out the Hiro seemed to know what the characters in the comic said even though they were written in English and we know that at this pointed Hiro don't know English. Any ideas?

well as we see in Ep 4. Hiro can time travel, maybe the person you see is a Hiro from the future, talking to Ando so he will join up with him to help him, at the End of Ep4 He could speak english, I think Hiro is a little bit more than what we all expect.
GO HIRO!

In japan english is their forign language class they always have alot of trouble with it but for some reason they can read it much better then they can speak it just to let you know

not to mention the pictures
