Elsa feels awful for making Anna feel bad, but she's honestly just trying to... to get Anna to see that they never really know how much time they're going to have together. Maybe if things weren't so grim right now, she would be a little more distraught about it- more maybe... it's because it's herself with the fatal wound, and she feels like Anna can survive without her, whereas if it were the other way around Elsa doesn't know if she would be able to cope. Anna has always been the stronger one, the fighter, after all.

She falls silent with a nod, deciding to save her energy instead of arguing with Anna or trying to make her see differently. Elsa allows her sister to continue dragging her to the store, holding onto the fact that Anna told her they were nearly there. She doesn't think she has it in her to be pulled too much farther. She tries not to make too much noise, hoping to avoid making Anna feel any worse.

When they do finally make it, it's an extreme relief.
