SION PONYTAIL SOLVED

Sion's ponytail (or thats what it looks like) is actually a flag. Let me tell you why.

In his 'Reborn' reveal (link below) it is stated that "He battled Jarvan beyond the point of breaking. He was finally bested......but not beaten." This shows that Sion fights a previous Jarvan, and get defeated. This must mean that Jarvan must've used alot of moves and strength. One such move could've been 'Demacian Standard' You got it. In this move, Jarvan (ingame) throws a spear which lands on an enemy, dealing damage. It also as a thin flag attached at the end of the spear. This shows, that Sion's head has Jarvans (past king) lance in it. Which is weird. Some pics below.
