See the little tickmark on the right foot of EVA-t and EVA-k? It's almost always there. Besides the fact that the leg is unusually long, slightly curved (which is not usual either), and the loop unusually large, there's no sign of a tickmark (serif) on the bottom-right leg of the mystery character.
It differs from EVA-k in too many ways for me to believe that this is a messy EVA-k.
