Loki frowned, brows drawing together. He couldn't see his mother's expression or gestures, only hear the note of strain in her voice, and he wasn't quite certain how to read it. "I suppose... I though it because we caused trouble enough for ten children, really." Because of course, growing up, his world had always been just mother, father, older brother. Why would there be more than that, or less?

Strange still, to think of it now that he was forced to truly realize that Frigga had only one son in the sense of blood, and that was Thor. But that was not so strange, was it?

"Volstagg and his veritable litter of children was the exception rather than the rule. Two seems a nice number." His lips twisted slightly as he fought the urge to dig at the fact that two, even if one of them was a cuckoo in that nest. No, Frigga was his mother in all ways that mattered, and that was a scab he would no longer pick. Let it heal.
