Tom must have had a growth spurt then. Or at least I think so...I guess we don't see the entire rock, so it's hard to get a good reference for scale.Also, what was your first hint that we like over-analyze things? The fact that we've given all the background characters names (there's a huge list on a certain wiki)? The sheer variety of theories that try to explain Luna's banishment, Discord's reign, and the nature of the changelings? The number of pieces of fanfiction dedicated to characters that appeared for less than ten seconds in the show (Octy and Vinyl, specifically)? Yes, the special talent of the brony community is reading too much into everything.
