Liz was trying to figure out a way to help. If they had been trapped in a way where it wasn't Peter keeping the entire thing from caving in on them, then maybe they could do something. Find some sort of lever to get the bigger rocks out of the way or something. As it was, they were stuck and she wasn't sure how much longer Peter could keep this up.

The amount of guilt that swelled up inside of her chest was immense and she heard Kitty's words at the beginning when she had first started to date Peter - she had promised Kitty not to put herself in a situation where Peter would do something rash and hurt himself. And yet, here they were.

"I love you." Which was said in a way that sounded like an apology, but maybe also a 'goodbye' in case they couldn't make it out alive. She was vaguely aware that her blinking was getting longer and there were longer pauses where her eyes closed before she managed to open them. "I just... I need to rest for a second." A nap sounded really good right now.
