Thor has only a glimpse of him, he is on the other side of the street, half-obscured by the car he is leaning against. He is pale. The flash that Thor sees of his face is sharp and angular. A strand of long, dark hair has fallen forward, it lies against one cheekbone, and Thor knows him, knows him immediately and without doubt, half-glimpsed and impossible though he be.
Thor does not think to question how. He does not think to question at all. His breathes, “Loki,” meaning it to be a yell.
