Disclaimer: 1,000 words of overly serious, ridiculous headcanon nonsense.
Glee, as a rule, tends to highlight how unique and individual every member of New Directions is, particularly by putting them against rival groups of mindless clones headed by a Charismatic Leader of sorts. First it was Sue and Quinn leading the cheerios, with their uniforms and perfect ponytails. Then it was Jesse St James leading Vocal Adrenaline, which I think were actually referred to as soulless automatons at one point. Now, if only because the writers are creatures of habit, the Warblers and Sebastian are filling this roll.
