Now that i'm a swiftie and a Marvel fan i realized that this lyric feets perfctly into Black Widow. Because she looks like a beautifull woman but she can kill you. There is a scene in the begining of Captain America The Winter Soldier that just proves it.
Ah, words can't describe the pain sometimes, but we have to believe in more, something bigger more meaning than just one person. We need to remember God is always there, always listening, put him first and he will always take care of you.
