@candrew: twilight was most likely about five when she hatched spike, which would make him at least five years younger than the rest of them. considering that they’re about sixteen to twenty-something that makes him still a kid, and therefore any relation he has kinda creepy.
^ I find it interesting that Spike’s fear is considered childish when it is the same as Twilight’s fear. Of course I’ve never really agreed with the fan interpretation of Spike as being that much younger than the mane 6 anyway.
A little kid with childish fears. I am glad being abandoned by twilight was his worst fear, and not that Rarity found the perfect colt. At least his priorities are in the right place.
