It seems like you have a really good start here. You give Alex a really unique personality (the whole "obsessed with history" I've experienced personally, so I found it funny), but I think it'seasier for people to relate to Andrew. You have an even amount of descrition and dialouge as well, which I find more enjoyable than just a bunch of talking.

It's very interesting, I'll have to keep an eye in this!

Ah, this is quite interesting. I suspect a lot of people are in Alexandra's shoes... as well as Andrew's.

Interesting thus far, really.
