Shielded in a titanium cell,
living in a serene state of solitude.
The cold world wouldn't harm,
but the cold cage did.
Beaten with insults,
scarred with fists.
Living an infernal life,
so I built an immaculate chamber.
A cell thought to be without flaw.
Frozen solid, but slowly shattering.
Only a warm heart could thaw,
and now mine's fluttering.
Stanza 2, line 2: scarred refers to being emotionally scarred.
Stanza 3, line 2: the subject of the sentence is the cage's captive.
Stanza 3, Line 4: this line is not referencing the cage's captive.
I'm tryin' not to spell it out, so that's why these notes are vague.
