On a trip to see friends in Manehattan, Spike falls ill and cannot be woken up. Without knowing why he's asleep, there's little hope of finding a remedy, but it's not as though anyone can just ask him what's wrong. Well, it's a good thing Twilight Sparkle isn't just anyone.

Twilight hasn't had occasion to travel into anypony's head recently, but if there were ever a time to dust off an old spell, this is it. The only problem is, she can't go in herself this time.

If only there were another talented unicorn in Manehattan who could help...
