If I should become a stranger

...know that it would make me more than sad
Caledonia's been everything I've ever had.

Hmm... I'm not sure what this is about but Loki obviously loves his home more than anything (more than his fake family at least, or so he'd probably claim, and if there's something more valuable then I don't know what it is). I really like Caledonia, it's a pretty song, and I also like how in the beginning of Hulk vs Thor there's Loki as the narrator voice.

He'd probably like telling someone about his home and what it was like growing up there if he wasn't such a bitter and twisted arse.
