She was in love with him....? At least thats the way I read that issue.
To that it seems its hinting at some kinda love feelings for Peter."All these secrets. All these things I can't say. I'll never be able to say. He'll never know...I-- I'm sorry, Peter....."
And I am not saying they are crying from sadness or joy. But from shock, shocked to see someone who is dead, someone they loved.
