Thor watches Zuko brush against the scar on his face, a gesture that mimics Thor's picking at his own. "Mine's been botherin' me too." He admits. "Think it's the cold doing it." Which is a lie, and Thor knows it, but he's hoping, in his own, clumsy way, that it might give Zuko some cover.

"Damn chill hasn't bothered me this much since my last trip to Niflheim." He admits. That's not a pleasant memory for him either, but he's older. Better he shoulder the burden than Zuko.
