For years now, Twilight Sparkle has been keeping in touch with someone she knew back when she was a young girl. Emails, chats, and the occasional mention to her current friends of this individual.

While they'd never pried into her personal business, all of them have at one point or another expressed curiosity about her friend; a boy by the name of Spike.

Of course, when they learn he's moving to Canterlot City, they might get their answers. Provided they can get over their first meeting.
