[ sadly, penny shakes her head. ]

I don't think I could change my future. When I return... I won't have much time left.

[ her last memory before waking up in verens was the sound of professor oobleck signalling the beginning of the match. she knows that if (when?) she returns, she'll be living the last moments of her life. ]

That's why I want to stay here for as long as I can. All of my friends are here, and I'm happy.

[ she's terrified of returning home, but doesn't say as much. ]
