In my opinion, America actually regrets his decision to be independent with him.

Why? Cause he needs someone to take care of him.

If he were to be sick, how can England cure him faster?

If America died, England would probably cry for weeks because he still loves America.

America's heart has a hole, like a donut hole. If he had amnesia, that hole will stay forever.

If he doesn't remember England's name but know what his face looks like, he'd probably sing these words to himself:

"Try one more time, a hundred times, but all I remember is your face, And yet you yourself, I'm not sure why I can't still remember you..."

If England found out that America has amnesia, he'll fall into a depression. France, Oliver or Japan will comfort him. Japan will also fall into depression because his best friend has amnesia.

America and England's relationship, in my opinion, cannot be broken. Cause if any of them dies, their relationship is gone, but it will still last. Their relationship will still stay, even though America is independent.

The fact that America hates England's cooking, he loves it, even Oliver's. No matter what happens, their relationship will stay for eternity.
