People say love is weak, but they're wrong: love is strong. In nearly everyone it trumps all other things - patriotism and ambition, religion and upbringing. And every kind of love - the epic and the small, the noble and the base - the one that a parent has for their child is the greatest of them all. That was the lesson I learned that day, and I'll be forever grateful I did. Some years later, deep in the ruins called Theatre of Death, it salvaged everything.
